Pretty good, for breakfast at a greasy spoon. I was there at around 11:00 am on a Saturday. Service was nice, the skillet was surprisingly good with tasty potatoes and fresh peppers, and the coffee fair.
Copper Top was clean, pleasant, and fairly priced. My only real complaint was the music...a little loud and a little weird. Lighting was crazy bright, but you could see the place was very clean because of that, so I'll call it a wash.
All things considered, Copper Top was just fine. I'd certainly go back.
