First off I want to say that I went with a group the started with 13 and ballooned up to 20. That being said, they could not handle 20 people. The waiter tried his best but he was just not up to the task at hand.
The dancing was good and if you like crowded, then you'll enjoy. Good music all around but the drummer did like one of his instruments a bit too much.
The food itself is a subset of the regular menu with large groups. It was very bland all around. Everyone in my group said the same thing, needs more flavor.
