Been here 3 times in 8 months, So I think I have a good opinion of the place.
Pros - Servers are very attentive and the staff is so nice and friendly. I think they do a great job at working together to take care of the customers. The place looks really nice and the menu is large enough to cover any desire you might have.
Cons - The food!!!! I ordered the chicken (chicken breast) and waffles. The chicken was sooooo dry. If you order this, get the chicken wings and waffles. Now onto the pancakes. I really didn't like them at all. While they are huge, they are not good at all. The eggs were pretty hard and just plain.
Conclusion - If you go to Stacks and Yolks, don't order Stacks or Yolks.
