If you're looking for a place to soak up all the alcohol you've had in Vegas, this is a good option.
Service was fast and I was ordered their regular shack cheese burger, and their cheese fries with bacon.
It came out to about 14 USD with a soft drink, not sure if the prices are on par with other shake snacks not on the strip.
Food came out in about five minutes and looked like the picture (unlike another chain starting with M).
The burger was on the smaller side, but fresh and not greasy. The pickles were crisp, and the vegetables fresh.
The fries were definitely decadent and delicious. The cheese is more of a processed nacho cheese. But hey I wasn't complaining.
Didn't get a chance to order a shake, because well I just thought that'd be a bit too much...next time I would just order plain fries or split the cheese fries.
Also, I did notice they had a veggie burger but that was mixed with cheese-so if you're vegan or dairy free. Probably not your best option.
