My business is a block away from Mr. Mama's, so I visit quite a bit. The great thing about this place is that you are greeted by the owner when you walk in and again while dining, and again when you leave. There are very few restaurant owners who meet and greet you in Vegas so this is really a nice touch.
The menu is simple and the food is great. Breakfast and lunch. The tourists from Las VEgas Blvd flock here, amazing and well worth the drive. If there is a line, usually only a 10 - 20 min wait, so no worries.
I don't eat beef, so no idea about the burgers.
The CHEF SALAD may very well be the best of Las Vegas. Also, Mr. Mama's makes most of its salad dressings, incredible.
Their french fry's are unique, not sure what is on them but so addictive.
The hash browns are to die for.
The Veggie omelet is also easily the best of Las Vegas.
The tuna sandwiches are great.
You really can't go wrong coming here...make the trip.
