Worst service EVER!! We had a party of 6 and made a reservation for 7:45. The restaurant asked us to push it back to 8:15. We weren't thrilled about that, but figured it wasn't a huge deal, we were not seated until 9pm. When we asked why such a long wait, they said they were overbooked, sorry but isn't that why you take a reservation? The wait staff was then slow and we didn't get out of there til after 11pm. I'll never go back.
