Come for the BBQ, stay for the dessert jars. We hit up Bell's BBQ while we were in Vegas earlier this month (July 2016). Tip: A Yelp check-in gets you a free side! The BBQ is awesome...moist and tender. I split a brisket plate with 3 sides (one free) with my daughter, so we would have room for the 3 dessert jars we ordered. Priorities...always save room for dessert.
Our dessert jars were: Red Velvet, S'mores and Crème Brulee. All were wonderful. The Red Velvet was my fav. I would come back just for the dessert jars right now if it didn't take me 10 hours to drive there.
Definitely worth a return visit next time we're in Las Vegas.
