Several people we talked to in Vegas recommended Egg & I, so we had to try it out. My wife and I both really liked the atmosphere. It was busy but they kept things moving. If you need anything, you can flip a cardboard egg on your table from black to yellow, and someone comes within minutes to see what you need. That, plus everyone gets a table-side carafe of coffee, were huge pluses.
Unfortunately the pluses didn't completely overshadow the fact that our waitress messed up both our orders. My wife's veggie omelet, hold the onions, was stuffed with onions. My Cali omelet, the special for the morning, for some reason and as egg whites. I didn't want to wait for another one, so I just ate it. It didn't have much flavor as a result. Nor did the cinnamon raisin toast my wife ordered. I guess just a disappointing breakfast all together.
