We love Kelly O's! We have only been to the one in the strip district. We have heard about the original but have yet to make it.
There breakfast is very hearty. The portions are large enough that you do not walk away hungry. You may even take some home with you.
The Italian bread/toast is great. I am speculating that it is the same bread Primantis uses for their famous sandwiches.
The orange juice is fresh squeezed and tastes amazing.
