Food was tasty but waitstaff was lackluster - kind of ruined the experience a bit. Note on the food - everything was hot and yummy, but small portions for what you pay ($13-35), that includes drinks too ($10). We came in on a Saturday night, with a large group mind you, and were prepared and happy to wait. We were told 45 mins and we honestly expected more. So we went up to the bar to grab drinks. We definitely were hitting the middle to end of the dinner rush and many of us work in the food industry so were happy to be patient and give the bartenders time as the bar was about 70% full. A bartender asked for our drinks and had asked "anyone else?" while taking one persons drink order so we gave her a couple at a time. When she came back with them, the other people in my group (2) both gave her their order right after the order and we were met with "you have to give me a second I can do only one at a time!!". Which, fair, but we were kind of taken aback by the tone after she had just asked for multiple orders at once. Much to our happy surprise, we were seated only 20 mins later. We were seated on the rooftop which unfortunately didn't have any heat lamps as we'd expected. Our waitress was friendly and asked for drinks. Brought us our waters and then proceeded to disappear for 30 mins. We wanted to order appetizers and she was no where to be found. Again, busy night, that's okay. But then we realized she had friends at the table next to ours and was sitting and talking to them while ignoring us and I'm assuming her other tables. We agreed we would just order our food too at the same time as appetizers since it seems to be a long wait for service. She came back, didn't apologize for the wait or anything. We ordered and our appetizers came about another 30 mins later, and then our food about another 15 after we'd finished the appetizer. Mind you, this whole time our waitress was talking to her friends and other people had brought us our food (2 peoples dishes had stuff missing from them). We heard her give her friends 25% off their meals (or something similar to that %) since they had to wait and because they were her friends. We had been sitting there the same time and they definitely got their food much sooner then our table, but we were not met with such discount. Hard to say if I'd be back again for dinner.
