B&C is so small that I think there is only spot where tables could be pushed together to seat 9 at one table; otherwise you'd be split up. You might have quite a long wait to seat that many. And quite honestly, I don't think the food is that good. We go there because we stay there but I wouldn't travel to BC to eat at Beaches & Cream.
The kids will enjoy 50's, you will be able to get an ADR, you will be seated together.
