It was surprisingly easy to get a reservation - everything was handled on-line via Cityeats which I like (I would much rather interact with a website than a human on the phone every day of the week). A few days before we got a call confirming our reservations and dietary restrictions - the fact that I don't eat meat would be cheerfully accommodated, however my mild chocolate allergy was hard to cater to as I was told several dessert courses have chocolate. I said we'd figure something out (maybe I could trade my chocolate to Ben for something delicious that I wanted more of!) and we were all set to go.
We picked the earlier seating (6pm - the other option was 9:30pm) and I'm glad we did as we were barely making our way out of there by 9:35pm after arriving about five minutes before six. We were escorted to a very lovely though tiny bar where we witnessed an awesome sounding cocktail menu:
The rest of the story will have to be told in pictures. I'm able to describe the dishes accurately because we were presented with exact menus of our dinner at the very end - but even so I took copious notes, and I was glad I did because the "tastes" - amuses but there were around ten of them - were not listed in the menu. And since it was early on, I was still focused enough to make detailed notes. After a while I lost all concentration as most of the time I was too busy moaning with pleasure or giggling with amusement to remember to take notes (at least I *mostly* remembered to take pictures).
TL;DR if you are in NY you should make an effort to get to Atera.
