First, overall it's a good deal and some fun. The brunch is good, not great, the venue is pretty cool and the location is excellent.
The guys are the same band that did Beatlemania 20-something years ago. Yes, that means they look pretty old and, frankly, kind of ridiculous, especially in those young Beatles outfits. None of their faces look like the Beatles' anymore. But they do a decent job of sounding like the Fab4. They're well-polished and seem to work hard.
It's a tourist crowd of course. I came in from the suburbs with my wife and 7 year old.
Our main complaint is that it's too loud for this kind of crowd. It was very loud. This is not Who tribute band, it's the Beatles in a fairly small club with old people and little kids in the audience. We ended up moving to the back row where it was more tolerable.
