We visited Casablanca this weekend with a group of six, and had a wonderful and relaxing time. The outside of the building, as mentioned in another posting, is very nondescript, but the inside has a casual, Arabian feel. The menu is prix fixe at $32.75 ($38.75 for the nightly special), which includes 5 courses. They do not sell alcohol, but allow you to bring your own for no extra charge.
The food itself was great - I had the nightly special (rack of lamb), but what was most wonderful about the night was the slow pace of the meal and the great conversation. Our reservations were for 6:30, and we got into the car to head home at 10:15. We could've finished more quickly, but were really enjoying each others company.
Overall, this was an excellent choice for a casual, relaxed evening with a group of friends.
