Surprisingly good. The owner is very intense while cooking, so it is not as fast as fast food, but he cooks things well. The fries have a good crunch and even though the bratwurst I got wasn't top quality, it was cooked so well that it still tasted good. You have no idea how often I have some artisan sausage at a restaurant that is ruined by improper cooking.
I'll have to come back to try the rest of the menu. It has everything from frozen cheesecake on a stick to tamales to gyros. I never would have guessed since this place looks pretty average.
