Went a group of 8, good atmosphere and great service. Tried as a group the Tapas Viet which covers a variety of their starters which were really good except for the dumplings which I found to have little filling. Main dishes are either a set of curries or a set of noodle soups (then there are other options like ribs, etc. but we mostly had these). The curries were great, mid-hot was hot enough, and we eat Indian in UK, lots of fish, prawns and squid in mine. The noodle soup that my wife had also passed the taste test with great ingredientes. Great presentation on all dishes.
Do recommend Green Bamboo if you are looking for something spicy in Buenos Aires.
