This restaurant is right in Severance Hall. A quick dinner right before the show would be the best way to go. They often will have a limited number of menu items so that food comes out fast. However, the downside is that the crowd crunch does affect the speed and efficiency of service at times.
They do not have a children's menu. On certain days, perhaps for afternoon shows, the have lunch or brunch. Not bad. I'd say this was A-OK.
