The Union Grill is one of my favorite restaurants within walking distance from CMU campus. It tends to be pretty busy around lunch so if you go at this time, be prepared to wait a while. They have a policy that everybody at a table needs to be present before they'll seat you that can be kind of annoying. However, their food is good. The atmosphere is casual. One of my favorites of theirs is their Pittsburgh steak salad. Their desserts are great too.
