Located in the MGM, near the casino floor, this is a decent place to grab your basic diner style foods. The food quality is wonderful, portion sizes are very large (leftovers for sure here! Sadly no fridges in the MGM rooms though) and drinks are refilled promptly. Prices are high, but in reality are acceptable due to portion sizes. The menu is huge and there is a small all day breakfast menu if desired.
Amazingly, there is no smoke smell despite being so close to slots which was a very welcome surprise. Avenue 24 is a good place to visit if you need your basic comfort foods; however, with all the great dining options in Vegas, I would say to limit this to one visit per trip.
