My wife and I were in Vegas on vacation, and went back to the Egg & I. We had been there about a half year ago (the last time we were in Vegas). Both times the food and service were good. Both time the place was very busy. Both times we were there closer to lunch time, so I imagine Breakfast time must be even more busy. The food is very good, and the prices are reasonable (no Las Vegas deal, but normal for a off the strip family place).
Next time we are in Las Vegas, we will be at the Egg & I.
