    Came in tonight for the first time, got a “Edgar Allen Poe.” (The pizzas have fun names) and the peppercorn ranch salad. I asked for extra ranch, but honestly they put the perfect amount on the salad, so I used the extra ranch to dip my pizza in. The service was fantastic too, multiple servers made sure we were taken care of, but we caught the names of Tristen and Payton- they were fantastic.

    First time at this place and it was great. Waitress noticed a mistake on our pizza before she even brought it out and had a new one already being made when she brought us the messed up one. I highly recommend this place.
