Not too bad, not that great either. I always get my orders to go and I always get the mushroom-swiss burger. I've dined in at the SmashBurger next to UNLV before though. The UNLV location is always a tad busier but service is superb.
SmashBurger doesn't really leap in terms of a burger joint over other burger restaurant. This location has mixed up my orders before and that's how I've had the privilege of tasting other burgers. lol. Other than that I always order the mushroom swiss 1/2 lb burger. My to go paper bag always leaks of grease or "juice" so I like to wrap my burger in layers of napkin on the way out of SmashBurger. By the time I get to eat my burger, the napkin absorbs so much of the excess grease.
Their healthier option are the chicken burgers. So it's not all bad.
