I haven't seen the episode of Diners Drive Ins and Dives featuring Four Kegs, but I would love to. This place has great bar food, not to mention some of the best pizza I have ever had! I haven't tried the Stromboli, but I definitely will the next time I am in there. I can't say the service is the best every day, but definitely not the worst, and the food is worth it.
It is true that the bartender will not, and legally can't take your order. Nevada passed a ban on smoking in places that serve food. Some of the more popular bars in town have had to figure out ways to still serve their loyal patrons food, while having a smoker friendly bar environment.
