I say use this place for cocktails.
We agreed, sitting at the corner of the bar that:
1. it was difficult to hear each other
2. the amount of krab mix on the menu was unfortunate
3. there was a noticeable lack of patio
4. we've had better service
There is an underground menu, but we only learned about that by overhearing the wait staff talking to other customers. They neglected the second half of our order, and finally we cancelled it and left.
Overall, I agree that this place seems like a great concept but falls down a little in its execution.
