If a game is rained out, is the bar still open on game day?

Yes. No reason that the bar closes for bad weather unless there is a hurricane or some other major weather event

Yes it is still open

Yes. It is open although rain.

Yes, but there's NO re-entry. Once you go into the game you can't go back to the bar.

Yes. It's a regular bar regardless of games

I believe that the bar will be open unless the game is called well in advance. which it never is or almost never is

I do believe it may be one thing I recommend it's expensive but get the homerun drink
