I've been here a couple times. First time I had a skillet breakfast and it was really good - not excessively salty like so many restaurant potato dishes. Next time I had to try their flavored pancakes. I picked the lemon flavor - oh yummy!
In general I'd say this place is pretty good. It gets busy at peak times and I think the staff sometimes gets a little overwhelmed. Everyone there is very friendly, though, and usually quite attentive. Also, the prices good and the place is clean. Stacks and Yolks is among my top 5 breakfast places.
