Kalmes Breaktime in Dubuque, Iowa
One of the best burgers I have ever had is at a little joint in Dubuque, Iowa. Kalmes Breaktime seems to be mostly a bar, but it's a very good restaurant as well. The burgers are great, and they are sized the way I like burgers, so you can pick them up and eat them. Plus they have a daily special. I think on Mondays the burgers are $5 with as many toppings as you like plus a side. It's on Jackson near 11th street.
