I'll second all that folks are raving about: great cocktails, great Khao Soi, crispy fish and green curry.
This place is terrific to go to with vegan/vegetarian friends as the menu is super friendly to both carnivores and not.
It's $$ for downtown but tapas style eating does add up.
It's noisy but fine enough for conversation if not more than 4-5 people (otherwise everyone has to shout).
Reservations strongly recommended! They are busy week round.
