I went to this place twice in the last month and had the same experience. It is impossible to get drinks at the bar or your table, and it also takes forever to get your bill.
All in all, the food is great. The ambiance is kind of cool and as much as I want to say all the servers are terrible, I seriously don't believe that. The bar just feels understaffed. One or two bartenders are responsible for servicing everyone at the very large bar area as well as the whole dining room.
I'm pretty easy going and it let me down twice (on a birthday and a date). Sadly there are other places in the city I'd like to try before going back.
