Casbah had some hits and some misses.
We started with the gazpacho and the mussels, which were the highlights of the meal. Unfortunately, the tuna (although marketed as being seared) was overcooked. The short rib ravioli seemed like a good choice, but was a bit oversalted.
My extra stars are more for Casbah's ambience. The covered and lit patio is pretty romantic, so I would suggest drinks and appetizers with a reservation on the patio. The staff was VERY attentive...maybe a little too attentive. But this was probably because we came on a Thursday. I've heard that it gets pretty busy during the weekend, so reservations are a must.
The menu overall looks really tasty, so I may go back to try a few more dishes...but not before trying some other places in Pittsburgh!
