Used to be a favorite spot for me since I oftentimes stay in the hotel, as it is close to the airport. easy to get to, and has ample parking close to the entrance/exit.
On trip last month, found out they no longer have the way late night specials. Not good, and really gives me little reason to choose Mad Onion above any other offerings that are a short drive away.
Used to have a great steak type meal or a breakfast for cheap. Now it's under new management, and the good old Vegas is yet one step from GONE.
It's a decent place that's not crowded with good enough food.
