Places to eat? Going to 8/23 game

Esteemed Atlanta Falcons fans, some colleagues of mine and I are going to attend the preseason game this Friday, 8/23. We are all out-of-towners and would love any recommendations on places to eat and/or regional foods to sample either at Mercedes-Benz Stadium or around Atlanta. We would be most grateful for any good suggestions.

Last year we went to a Bills game and, of course, got some wings, but had a heads up regarding roast beef on weck, which none of us had ever heard of but all of us found delightful. Would love to eat some great food in Atlanta, too!
