I'm long overdue to review Pepe's, seeing as I've checked in enough times to warrant a cot in the back. This place serves the *best* street tacos in Las Vegas at a great price.
Once inside, the friendly staff does a good job keeping the place clean, and the salsa bar stocked. They also always have a large portion of spicy carrots and chopped radishes. The red salsa has a nice heat with great flavor. I would take it intravenously if I could. And here's something else unique about Pepe's: Free refills on Horchata and fruit drinks (holy crap!). That right there is one of the best values in town.
The tacos themselves are glorious. I almost always get the chicken tacos with the 3 taco special which is served with beans and a smattering of chips. The carne asada is also *very* good, though the el pastor is just kind of "meh". What I love most about this place is the consistency; the tacos are always delicious, always hot, and always made exactly the same. This is in contrast to some other locations *cough* Rainbow and Flamingo *cough* where the product ranges from palatable to "Dear god, did one of the cooks find an old horse dead in the street on the way in to work?". I would seriously eat here 4-5 times per week if my cardiologist hadn't threatened me with an anesthesia free heart procedure if I didn't cut back. This is one of my "go-to" places in Las Vegas for friends and visitors alike.
Some find the location (Boulder Highway and Flamingo) to be questionable, but just think of it as dinner and a show. On the plus side, this location seems to attract a surprisingly attractive group of prostitutes, so bring the kids and play a rousing game of "Spot the Hooker". It's fun for the whole family!
