Bui’s

If I could give no stars, I would. Got food poisoning here. 0/​10, would not come here again.

A friend recommended Bui’s after he heard me raving about Lyns… I will now only rave about Bui’s.
Simple concept: egg sandwiches on hoagie rolls. What sets them apart: Lots of ingredients (no skimping on eggs or veggies), fresh veggies (tomatoes, mushrooms and spinach) and of course, the famous special sauce (mix of mayo /​ketchup). For $ 4.50 you get a huge, delicious and warm sandwich — perfect cold day fix.
Can’t wait to be back!

I never got why Bui’s is so apparently awesome. I must’ve missed the memo…
It’s alright. I’ve gotten a couple of the specials, and their subs are typically made with a combination or ham, egg, cheese, and/​or condiments, wrapped in foil and ready to eat. I get that it’s cheap and convenient, but so are most of the food trunks along 38^th or Spruce.
Someone tell me what I missed, please!!!

Very good and fast sandwiches. Just had sausage and egg on a large roll for only $ 3.75. Always gets you the sandwich quickly. Open 7 days during College school year.

Bui’s was my first ever Penn food truck experience (thanks to an extremely hungover friend who asked me to get him a Hangover Special from Bui’s) and I must say, it blew away the standard I held for food truck breakfast sandwiches! I had ordered a simple ham, egg white, and cheese on a bagel with light ketchup and pepper. Though the sandwich is uncomplicated to make, it’s the fact that it wasn’t greasy and sloppy — that is what impressed me about Bui’s. The egg wasn’t wet and slipping out, the cheese wasn’t gooey and running down the sides, the bagel wasn’t hard to chew — just none of that! It was a simplistic and beautifully prepared sandwich, especially considering since there was a crowd of hungover students waiting to get their food as well.
Bui’s is definitely a good option to consider whether you’re hungover or sober, taking a lunch break, or grabbing food to eat while binge watching Netflix,. Quick, cheap, and made with love, the people at Bui’s definitely know how to make breakfast sandwiches.

Penn’s famous sandwich cart. I’m always a fan of supporting my fellow Viets, and when I found out there were making sandwiches of all things (and not Banh Mi), I didn’t know what to expect. Ordered from the specials menu because that’s where it’s at, and got the Hangover Special w/Bui’s Sauce and the Mr. Bui w/​steak.
Hangover Special (3.5÷5): I guess I really don’t get these breakfast sandwiches for the most part. It is indeed a filling sandwich, and I was not unhappy with it. But given the ingredients (egg, cheese, bacon, ham, sausage), it’s not terribly complicated to make and something I feel I could easily re-​create at home if I bothered to.
Mr. Bui (³⁄₅): Seemed like a beef teriyaki sandwich essentially. Nothing to write home about. Didn’t hate it, didn’t love it.
I’d probably stick more to the breakfast based sandwiches though because they pair better with Bui’s Sauce (gotta love mayo and sriracha). As a sidenote, I find it funny that the most popular sandwich carts in Philly are owned by Vietnamese people, but don’t sell the most popular Vietnamese sandwiches (Banh Mi, where you at?). While none of the flavors are particularly impressive, the combination of Bui’s sauce and breakfast classics means that Bui’s will never let you down for a consistently tasty and filling sandwich.

A lot of people have called this great hangover food but my best friend introduced it to me as «Netflix food.» She calls it the kind of guilty pleasure food you want to hold close to your chest and happily nibble on as you watch your favorite TV show and bum around on a weekend day (while procrastinating on homework, of course).
I tried the turkey bacon, egg, cheese sandwich and was pretty blown away by how satisfying and tasty it was. Make sure to eat it while it’s still warm. I was also so pleased to be able to choose turkey bacon (instead of regular bacon) as an option. Can’t find that in most places! Additionally, the spicy Bui sauce definitely takes the sandwich to the next level. I expected it to be a red sauce but it turned out to be white — interesting! Basically a spicy mayo. Can’t wait to enjoy one of these when I visit Penn again!

The special Bui sauce. hm. tangy, spicy, it’s a mixture of some not so common Asian flavor. Price is cheap, but flavor is just ok. Also it only opens rush hours, so if the doors are shut, it means shut. I tried meatballs and some steak sandwiches. They are okay. I think meatballs is little heavy with binders and hard to taste the meat. I can tell the sauce is definitely some jar brand.

Meh. Don’t get me wrong, I love food trucks. But the cheese philly I got was lacking big flavor. There were so many great reviews that I was expecting some serious food here. Prices were great… but I wish there was more flavor.

It’s one woman back there cooking and handling money so I understand that she’s swamped and may take a little longer to get to you. The food is just so overpriced compared to the other food trucks. 4.50 for bacon egg and cheese is way too much. I don’t know how they are still open when you can get the same at Hemo’s for much less.

If you’re in the mood for some delicious sandwiches in UCity, Bui’s is the way to go! After having heard so many good things about this food truck, I finally gave it a try. Since then, I have continued to come back almost every week! Bui’s has cheap, great sandwiches AND they are prepared in a super fast manner. My favorite is the hangover special, a very popular choice among other customers as well. It’s filled with a sausage patty, bacon, eggs, and their special Bui’s sauce. The Bui’s sauce is most likely a combination of Siracha and mayo sauce, but the way they make it has a tasty kick to it! It’s a delicious addition to all their sandwiches!
The owners are Vietnamese and friendly! You also have the option to call ahead and make a phone order for pick up. I’ve also called and asked them what their hours are and it actually closes around 2:30−3p. Bui’s is perfect for a breakfast or lunch sandwich!

Best breakfast cart in University City. If you’re a Penn student, you know Bui’s as THE magical hangover cure on campus. If you aren’t hungover, it’s still a filling, cheap, delicious way to start your day. I usually get the veggie special with Bui sauce (some heavenly combo of mayo and sriracha) and I highly recommend you try it too!

After years of patronage, I can’t believe I haven’t written a review for Bui’s. This is the perfect food cart in my eyes: family run, cheap, interesting, and delicious.
I’m ashamed to say we get the same damn thing every time, because we love both items: Mrs Bui and the Hangover Special with Bui Sauce. I swear, we drive twenty blocks each way just to get our fix on Saturday and Sunday mornings.
When you’re in the mood for a filling, awesome sandwich, look no further!

I always get a Mrs. Bui. Solid sandwich.
This is the best place to go for breakfast or lunch. The sandwiches are fairly cheap, and the people are fast. There will most likely be a line, but it is definitely worth it.

«Salt peppa ketchup Bui sauce?» Always Bui sauce. Always always always.
Every breakfast sandwich from Bui’s is on point on point on point. Super SUPER filling, delicious, cheap, and with quick service to boot! The long rolls are always so delicious and wonderfully chewy like some kind of magic French baguette.
Again, they’re pretty fast, but even so, if you don’t want to wait, you can definitely order ahead! :)
Last I checked, unlike Lyn’s, Bui’s is open 7 days a week. Lazy weekend mornings are made all the better with a Bui’s breakfast sandwich.

As far as a breakfast sandwich at a food truck can go, this is the best it could get in my opinion.
I had turkey bacon with egg and cheese on their longer rolls with some creamy sriracha sauce. First of all, the fillings were incredible, but its hard to mess up egg and cheese. The bread was what really set Bui’s apart. I’ve yet to have another breakfast sandwich with such delicious and fresh bread. Will go back for sure.

So glad I tried this food truck out finally! I live right around the corner and decided to try this place today. Cheap and good sandwiches? AND fast service? All possible thanks to Bui’s. Sandwiches range from $ 4-​$ 6. They have a menu, but really, you can just tell them what you’d like in a sandwich, and they would make it for you.
I ordered the steak and eggs sandwich today with onions. My boyfriend got the pork roll, eggs, and cheese sandwich. The sandwiches are pretty big and filling. You can order with ketchup, salt, pepper, or Bui’s sauce. Bui’s sauce is a mixture of probably sirarcha and mayo. Tastes like spicy mayo really. Good stuff to top your sandwich with! The steak and eggs sandwich was great for what it is. Basic sandwich and simply delicious! Wish I added mushrooms to it! That would’ve made it a whole lot better. The pork roll and egg sandwich was probably my favorite from today though. We got Bui’s sauce to go with it, and it complimented it pretty well. If you’re in the area and want to grab something quick, cheap and good, definitely come to Bui’s!

One of the best, if not THE best, food truck in West Philly.
All of their sandwiches are really, really good — filling, tasty, and cheap. I’m a huge fan of the Mr. Bui and the Mrs. Bui, and get them with Bui’s sauce — some sort of sriracha mayo thing, but it makes everything better. Everything else on their menu is great too, and you can get the staples like a BLT/​egg sandwich/​cheesesteak too. They also have Orangina sometimes as a beverage item, and who doesn’t like that?
Mr & Mrs Bui are really friendly too, and once you’ve been there a few times, they start to remember your order. You can also call or text in your order for pick up which is really convenient if you’re in a rush and want something quick to eat.

Come here if you’re on a mission to cure your hangover or if you’re just craving a huge sandwich! I love that Bui’s doesn’t overcharge — the prices have remained pretty much the same in the past three years. My absolute favorite is the Mrs. Bui with beef — spinach, tomato, hot sauce, Bui’s sauce, and onions. YUM!
Also you can text your order in, which is useful when everyone is hungover on Saturday/​Sunday morning and there’s a line to order. But typically they are super fast, I’ve never waited longer than 10 minutes to get a sandwich.

A five star food truck? Is it possible? Is this the apocalypse?
Bui’s wins on almost all criteria:
–Taste? Check, that Bui’s sauce is a must for any sandwich
–Cost? Check, $ 4 – 6 dollars for anything. Cheaper if you’re looking for a simple breakfast sandwich or cheeseburger.
–Convenience? Check, call or text your order in and you can enjoy your walk over to 38^th Street in peace.
–Service? Check, Mr. and Mrs. Bui are super friendly and will always put a smile on your face.
–Hours? Check, open seven days a week for all three meals of the day. No other place can boast that kind of commitment.
Five criteria, five checks. This puts Bui’s in lofty standing among food trucks.
