Q: Really displeased with the service we received. Made reservations with co-workers for 7:30, and were seated by 7:35. However, from the time the waiter took our drink orders to the time we received the drinks was about 30 minutes. The restaurant was about 25% full.

Once we were able to order, everyone ordered an appetizer salad and an entree. One of us asked for anchovies on the Cesar salad. 4 of the 5 salads arrived around 8:45.. no anchovies. My salad never came out, and our waiter was nowhere to be found.

Once the food arrived, the anchovies were found on my co-workers pizza instead of the salad. I finally found the waiter, and I asked what happened to my salad and he sent over a manager. She told me she'd ""go ahead and take the salad off your bill""... which I was like, ""thank you for not making me pay for a salad I never received"". Are you serious?!!?? Then she gave me a ""free"" piece of cake. I don't understand - I wanted a salad?

The rest of the food was ok, nothing spectacular. I had a pepperoni calzone. The decor of the place is very cool, and they have some great music. But if you want to have dinner in less than 2 hours and receive great service: I'd go elsewhere.
