Smashburger in Wichita at Woodlawn & 96 hwy...the haystack onions are GREAT!
Near the downtown arena on Broadway is the Artichoke, best sandwiches in Wichita
Granite City is also good...gotta love the Idaho Nachos
And for all of you Taco Grande fans...there are two locations that I know of in Wichita..one on 21st street and one on Seneca
