Atlanta has a similar thing, but the exclusive club is right there by the seats. Our former vet had those seats and gave my family tickets when the Brewers were in town. It was incredible. Obviously great seats, but the club was incredible.
Enormous and basically anything you could ever want to eat, and as much as you wanted. We got there early and ate before the game. It remained open during the game, but IIRC, not everything was available. We went back in between innings once or twice.
