I'm VERY impressed!
Yes, the food is typical diner fare, but it is VERY good diner fare. With rare exception, the food is absolutely excellent (skip the banana bread...it's glazed and it shouldn't be).
You really can't go wrong with anything here. The full menu is available at all times, so if you want a big burger for breakfast, you can get it.
The ambiance is really charming, and the music is top-notch. A rare gem in downtown Glendale!
