1. Wrigley Field. There's just no better place to watch a baseball game.
2. AT&T Park (or whatever it's called now) in San Fran.
3. Mercedes-Benz Stadium - really nice venue, great concessions prices.
4. Superdome - got the dub vs. Clemson, and they serve jambalaya and Dixie beer in the concession stands!
5. Coors Field - the view of the Rocky Mountains is really cool, as is the beer selection.
Other places I've seen games that don't make my top 5: Neyland Stadium, Starkvegas, Vandy, LP Field (Titans), Truist Park, Petco Park (San Diego), Miller Park (Milwaukee), both White Sox stadiums (old and new), Fenway Park (historic, but that's really all it has going for it), Yankee Stadium (not bad), Minute Maid Park (Astros), Tropicana Field (Rays - just awful), Georgia Dome (Falcons).
