I don't know where the dissatisfied diners ate, but I found Stacks n Yolks to be perfectly delightful. The service was fast and friendly. The food was well prepared and tasty and we got multiple refills on our coffee. The facility was clean and I really liked the multicolored wood wall.
I often have a problem with restaurant prepared breakfast potatoes being too greasy for me. The potatoes that came with my Eggs Benedict were just right and the poached eggs were properly done. My daughter's breakfast skillet was also very nice. It must have been good since she wasn't able to finish the whole thing and took the leftovers home with her.
I'll definitely be back!
