Eleven has a really nice happy hour special and I enjoy coming here for oysters. The restaurant is enormous and offers many types of dining experiences (there is the upscale dining area upstairs, the casual bar, and the intimate patio outside). I like to dine in the patio and look out at the industrial buildings of the Strip District.
This is a great place to visit for an intimate dinner in Pittsburgh. I also recommend getting a bottle of wine from their comprehensive selection!
