Otto Moser's is an excellent deli located in the Theater District. It's actually the oldest restaurant in Cleveland; it used to be in a different location (it's in a relatively new space where it's been for 14 years). The room is pretty spacious. There is a bar as well as tons of tables. The owners were walking around the restaurant and serving while we were eating there, which is always nice. I had a sandwich, of which I can't remember the name, that had roast beef and pastrami on rye. It was superb. The meat was perfect. The only complaint was there was more roast beef than pastrami, but that's no big deal. Overall, if you're in the Downtown area and are looking for a great lunch spot, Otto Moser's is the place to go for a little bit of Cleveland nostalgia (there are a lot of old photos on the wall) and great deli food.
