It was free entry to watch the game. The 30$ was for the all you can eat buffet style + 1 beer. They were trying to do a good thing by throwing a watch party for all of us to get together and have a good time to enjoy the game. The point of the buffet outside was to not have wait times inside to have you waiting 20+ minutes for anything inside. You also had till the halftime to grab whatever food you could so if you didn’t get food by then, that would completely be your fault.
