I've been to Katy's a few times for breakfast only. Each visit was first thing in the morning, so there hasn't been any sort of breakfast rush or even a slightly busy restaurant.
The only thing I've ordered has been the blueberry pancakes with their Black Label bacon. The bacon is very good; crisp with a high meat content. The pancakes are offered with plenty of butter, syrup, and blueberries. The cake is fluffy and light, but because of the size, I seem to always leave a little pancake on the plate. It's a good breakfast if you like pancakes and bacon, can't tell you about anything else there.
