ESPN club has 2 areas, one is the bar area, and one is the family oriented restaurant. If there are no big games and you are there at lunch, you can eat in the bar side with little drinking going on. The kids can play a playstation 2 game while waiting for food at no extra charge.
As for the food, IMO, ESPN is a lot tastier for roughly same cost. Waitstaff is very good. BRG is good but I wouldnt go out of my way for it. ESPN, I would make a special trip for. Not just for the atmosphere, but the food was that good.
