It's one the north side of town but I've hit the Dave and Busters on Wednesday night the last two years. Wednesday is 2 for 1 day.
Also, two years ago, my nephew and I did the Colts/Giants preseason football game on Saturday night. It was a very different break from gaming but it was a good way to shut off the brain for a few hours and yell at other people playing. Unfortunately, this year football starts later than GenCon.
