Dotty's is a college-y burger place that's right off of state street. This would be a good place to take your parents if they're visiting from out of town. It's an actual restaurant where you sit down, are waited on, get cutlery and dishes (although it might be just baskets). Dress is very causal, but you won't stick out if you're not wearing college kid clothes too bad.
As far the menu, it's like slightly fancy burgers and fries.
Fancy = more than just ketchup for sauces.
Burger and fries = lots of burger variations and stuff from the deep fryer.
