I love BW....that's the one place my dh said he would consider buying into DVC at...which we did, sight unseen.
But, do I recommend that people head over there, at night, for the activities? Nope. Disney made some cutbacks shortly after we bought there. There just wasn't as much going on. There can be jugglers, or magicians performing at night. Or, musicians. But, really? Other than that? Not much. There are a few carnival type games. And while there are shops there, none of them is very distinctive. Pretty much the same stuff you can get anywhere else at WDW.
So, sure, if you're at either Epcot or DHS and want to kill an hour or so, head over.
I like Jellyrolls as well...but it is for the over 21 group, which limits it for families. And there is no food there..other than popcorn.
