If you are in town early Friday, I would suggest you go to Swenson's for a burger. Pretty legendary place for Akronites.

Some others would suggest Skyway for a burger.

If you are a craft beer drinker, I highly recommend going to the Hoppin Frog tasting room. Great beer. Food, not so much.

Thirsty Dog is an early option. Tasting room open until 8 on Friday.

OBC's tasting room is open one hour later until 9.

Right across from the stadium are Manny's, BW-3, Europe Gyro & Pints.
For gameday, you have to come tailgate with the Zips fans.
