B&C is GREAT! They make some amazing treats -- for the very brave of stomach there's the Kitchen Sink. (URP!)
As BrianTime said, it can get very packed around lunch, dinner and especially after Illuminations. (Sometimes I think 1/2 the people from Epcot decide to stop for an ice cream treat after the show!) Try to stop there mid-afternoon, early evening or mid-evening. My DW and I managed to snag 2 meals (dinners) there plus an evening snack. LOVE IT! The proximity to SAB pool makes it popular for the swimmers plus it's the refill station for YC/BC refillable mugs. Sometimes the carry-out line will stretch out the door and then some.
However, even if you have to wait (and they have pagers, so you can wander the resort, check out the game room, get a hair wrap, etc.) IT IS WORTH IT.
