We visited The Harp while on a three day trip to Cleveland. Met up with a friend from the area, and she recommended this place. Although it was a Friday evening, around 6pm, it wasn't overly crowded, and the atmosphere was lovely. I loved the booths, they were super comfortable, as well.
The bread they brought out prior to the meal was very good. I'd never had Irish Soda Bread before. I'm a fan! I ordered the Spicy Grilled Chicken Sandwich with the hand cut fries. The sandwich was VERY spicy, so if you're expecting just a little kick, I'd go elsewhere. I really enjoyed it, though. The fries were excellent.
I would definitely return if I make it back to Cleveland in the future.
