If you’re a fan of old-fashioned diners, don’t miss Rotier’s. This little stone cottage is surrounded by newer buildings but has managed to remain a world unto itself. Sure, it looks like a dive from the outside, and the interior doesn’t seem to have been upgraded in 40 years, but the food is good and the prices are great. The French bread cheeseburger is said to be the best in the city, and for bigger appetites, there’s a meat-and-three option (minute steak, pork chops, fried chicken, whatever, plus three vegetables of your choice). Rotier’s is also good for daily blue-plate specials and cheap breakfasts.
