The food here is pretty good, and so far it's one of my favorite diner style restaurants in Cleveland, more for its relaxed atmosphere than anything else. There's counter seating that overlooks the grill and about 10 tables, so it's fairly small and cozy. The folks that run the place are authentically friendly, and you get just the right amount of service that doesn't cross into annoyance like many chain restaurants.
Sammy's closes early, just like everything else in downtown, so make sure you check the hours before venturing out to find it. I walked past the building several times looking for this place before I realized it was inside the same building as the Holiday Inn Express. You'll have to walk past the hotel parking kiosk to get in.
