I am a little biased with snacks but as for popcorn, Garretts is the best! This place is interesting because the line is separated. It begins at the store then continues a few stores down. Don’t worry, they are great at line control. They give you a menu so by the time you make your order, you can get an idea on what you will be ordering then you end up getting a bigger order because you finally get to see the popcorn! I spent about 3000 yen. *gasp* Since I wanted to share the love with my coworkers and friends. Although they don’t carry the specialty flavors and the sizes in the US, this will satisfy your popcorn cravings.
