B&C is one of our favorites. We've been there 8 times, and have only been to wdw twice.
It is very small, so if you go at a busy time the wait can be very long. We've always gone either when they open, or around 2, and have never waited.
Never tried the kitchen sink - too many things all mixed together for our tastes. Saw it being made though, and that was fun.
Some of our favorites are roast beef sub, double cheeseburger w/bacon & grilled onions, onion rings, fries, No Way Jose sundae, and Frozen Sunshine.
