Wanda's is a basic Diner with a Mexican twist. I've eaten here once and it was good enough that I'll be back.
The food was fresh, fast and good. I had a very basic scrambled eggs with cheese, hash browns with onions, toast and bacon. This breakfast for me is the yardstick for judging Diners. The eggs were perfect-not firm and overdone, not the least bit runny. Toast, bacon, potato's were just right as well.
As Amy B said, the space is on the small side and seating is limited.
A hands down winner over IHOP, Denny's or any other chain Diner.
