I've come here the last few times we've visited New Orleans and it has always been a pleasure. Service is great, food is excellent and the special is usually delightful! Prices are good too.
We were there on Lundi Gras, and the special was King Cake Pancakes. (!!!) My friend ordered them and said they were amazing. I was too stuffed from my basic breakfast of grits, sausage, eggs and a delicious biscuit, so I didn't dare try it myself.
The only problem with the Ruby Slipper is the wait. If you come at a peak time, you might be standing on the curb - or in the case of this visit - all crowded around the front of the restaurant, and the people who are trying to enjoy their breakfasts there. If you can hit it early or late, and get a table in the back, you will never be disappointed.
Pros: Food. Service. Grits.
