Downtown Knoxville on game day can be crazy. Cumberland Avenue, also known as the strip, is always hustling with college students decked out in orange and white. Where can you and your family actually get a place to sit down and eat and watch the game if you don't have tickets for the game? The first place I recommend is Buffalo Wild Wings(1912 Cumberland Avenue Knoxville, TN 37916), Downtown Brewery and Grill (424 South Gay Street Knoxville, TN 37902) and Calhoun's on the River (400 Neyland Drive Knoxville, TN 37902).
If you're looking for somewhere away from campus, but still in Knoxville, you can go to Calhoun's Bearden Hill (6515 Kingston Pike Knoxville, TN 37919) and Smoky Mountain Brewery in Turkey Creek (11308 Parkside Drive Knoxville, TN 37934).
I hope this helps! Happy football season!!
