My dd has celebrated a few birthdays at WCC, and all of them have been memorable, but the two that stand out were when our waiter had her stand up on a chair while everyone sang to her, then brought her a cupcake with "dirt" and gummy worms...for breakfast! The second was when we were traveling with my SiL and BiL and they made all of us ride the stick ponies around the restaurant singing "Happy Birthday". The rest of the guests agreed with the waitress that we weren't loud enough, so they made us go out into the lobby and ride around the Christmas tree, singing loud enough for them to hear us back at our table. It's a great place for birthdays, we always have such a great time there.
My sister had her wedding dinner there with about 60 people or so, and it's just as much fun in a large group!
