Seemed full up today. Saw the Tangled show, which was very cute, and it seems they are mixing the shows in the theater, which is a cool thing. It's a very small place, but detailed out like the rest of Fantasyland and I thought they did a nice job on it.
The first time my gf and I dropped in last Mon./Tues., it was busy but not overwhelmingly so. The second time we went through there(later that day, I think) it was a ghost town. I found it to be cute and well decorated but not too impressive. Perhaps we'll try seeing one of the shows sometime.
