The food is amazing, the cocktails are great and on weekends, after 11PM (or 12AM I can´t remember, too many cocktails) they have a DJ playing in the restaurant and things get jazzy, with people dancing on the tables and turns the entire restaurante on a dancing floor. And you can stay sited on your place, if you don´t feel like dancing also.
It is a great place to have dinner and have fun and it closes at 3AM, perfect timing to have fun and don´t destroy your day after with tiredness. I recommend you to try to cocktails "Cosmopolitan de Shanghai" and "Mojito Japomex".
Mandatory foods to try: Costillas de Res en Teryaki (backbone rib on teryaki sauce) and the gyozas, they are amazing.
