My husband and I ordered 2 glasses of wine, a gluten free pizza and dinner salad. The server brought our wine and our dinner salad which we were splitting as a first course. Once we were finished with our salad and awaiting our pizza, we were told that the kitchen had just informed our server that they were out of gluten free crust and would we like to see there menu again? Really? And what, wait another 20+ minutes for a meal to be made? We opted for a quick bowl of soup which was just ok. There way no offer to comp anything for our lack of a dinner, even though our server brought it to the managers attention. On the way out, my husband talked to the manager who was unsympathetic and his only solution was to talk with to the kitchen later. We've been to this restaurant several times but will not be back again.
