Map Room has good pizza and is a great food/drink stop to any night out downtown. I've been here a handful of times and have yet to see any other item on their menu come out of the kitchen at any time of the day. They also have a reasonable selection of beer on tap and prices are quite fair for downtown. If you're lucky, you can grab a seat at one of the two couches in the back by the fireplace during Cleveland's innumerable cold months. For the summer, the outdoor seating area is a great spot to sit, relax and get your fill of vitamin D.
As other reviewers have noted, it can be hard to get good service here, especially as it gets busier later in the evening.
