Wayne & Larry is a decent place to munch. The taco salad bowl is just ingredients piled up but with a little extra salsa or sour cream - pretty good.
Firecracker pasta is chicken and cheesy with jalepenos in a large serving. Burgers are made from the same beef you get at so many places in town that use Sysco.
I think for Lawrence, you get a place with tvs, trivia night, and they offer a lot of coupons in publications around town. Bring a buy 1 get 1 and you get a good deal.
I think a kids menu or healthy french fries or steamed veggies would help bring kids from the alley to the restaurant.
