My wife and I go to Best Friends for Sunday breakfast/brunch probably around twice a month. Nothing fancy, just your standard breakfast fare: eggs, omelets, pancakes, waffles. But the food is very consistently good, and the wait staff is absolutely fantastic; always extremely friendly and attentive. Even with a big breakfast and a generous tip, we can easily eat there for under $20 for both of us. We have tried a bunch of other places like it around Mentor, but nothing else has come close.
We have been there a few times for lunch and dinner. While the staff is still just as nice, the food isn't as good. But for your standard, nothing fancy American breakfast, you can't go wrong.
