Etihad Buisiness and First Lounge

I had the pleasure of using using one of the really nice lounges in Heathrow on my trip to India for Diwali. I had silver status membership on their scheme which allows lounge access so it would be rude to the company to not take advantage. The lounge itself is below the sky team lounge which is opposite gate 10 on terminal 4 and initially a little difficult to find though the attendants were very helpful.
On arrival I had a tour of the lounge with a very nice lady who later dragged me out when the flight was departing!
Whilst the lounge itself is noticeably smaller than other Heathrow lounges the interior is quite luxurious with comfy leather seats and a range of amenities. The service is generally good with attentive but not intrusive staff.
The extra amenities include a six senses spa, an a la carte menu with a buffet, the usual range if drinks a and business centre facilities. At the six senses you can book a range of treatments that each last 15 mins from hand massages to wet shaves to reiki treatments. Sadly there was no capacity today (though the website encourages booking on arrival)
In terms of the food I only ate from the a la carte where the portions are small and manageable pre flight the baked cod I had did appear a little dry. As mentioned there is a (actually quite good looking buffet menu too.
In addition to the above there is also a prayer room and baby changing facilities but no shower which would have been welcome.
Generally a great lounge squeezed into a small space that is particularly good as if you have silver membership there is access no matter what class you fly.
