Absolutely the worst IHOP we've ever been to.
We got there on a Tuesday morning after seeing how packed The Egg & I was and while most tables were full, there was no reason for the horrible service we got. Our waitress took a long time to even come over and get drink orders and then even longer to bring them. Then, when all of the food came out (we were a party of five), my husband's never showed up. She came back twice during the meal to tell him that it was coming, but it never showed.
The rest of us were done eating, plates cleaned when we finally told her to just forget his omelette meal. As usual, she made up some excuse that the kitchen was understaffed at the moment--though the other four of us and everyone else around us (most who showed up AFTER we did) got their items.
Just avoid and try one of the other breakfast places around. It's Vegas, you're bound to find something.
