I can honestly say that this place has one of the best burgers I've had in Las Vegas. It's totally a little joint & the interior needs a bit of work but it's clean, which is what matters the most to me.
They only serve burgers with the normal accoutrements but you won't need or want anything else. My burger was perfectly seasoned & cooked exactly the way I asked for it. The fries were delicious. The cashier/chef was super friendly and attentive even though he was the only one working. They seriously need to open another location where they can get more people in - Burger Lab is a hidden gem! It was worth every bit of cholesterol!
