DBF and I went last Wednesday (10/22 I think?) for lunch, about 1 p.m. and we were able to get seated right away, and even were able to pick where we wanted to sit. If it's a place you really want to go, I recommend going during the day. When we walked past it on Friday, 10/24, it was very crowded, I would guess the wait was over an hour.
I agree with others, the food was typical chain fare, and they are going through the normal growing pains of a new restaurant. That being said, I'd probably eat there again before Rainforest, because the themeing is really cool.
