I'm one who would have preferred something else be in that spot, closer to the old ESPN...I decided I'd try Cake Bake when it opened as Boardwalk is my home and I wanted to at least give it a one-and-done. But I'm not interested at all in the bakery portion - just the restaurant. Prices were ridiculous initially, but did adjust downward a bit - it's still one of the moderate to higher priced spots. Expectations were that I wouldn't go back.
But I found the food quality to be very good, service was very good, and my final bill really wasn't any different than most of the other Disney restaurants I eat at (Steakhouse 71, Tiffin's, Topolinos, etc). I have actually gone back 2 more times since as it turns out to be a decent spot for good quality food when I'm staying at Boardwalk. I'm not at all into the aesthetic - too frou-frou for me - but the food's good so that's what's really most important for me. I don't think I'll ever eat a desert there, but I'm not a real desert kind of person anyway.
I still want a sports bar, American food, or moderate restaurant option at Boardwalk again, so I'll keep hoping - given the choice to keep Cake Bake or bring back ESPN, I'll bring back ESPN every time. If they can put something like that in the Big River Space, that could appease me and I'm OK keeping Cake Bake around as an occasional choice.
