At first, I was really confused if I had gone to the wrong restaurant. There are no signs outside that say El Santaneco, but Restaurante Guatemalteco. It's located in between the green Beat the Bookstore and the USPS.
All the reviews are true guys, they've really got some mean pupusas here!!
Now I'm no pupusa pro, but compared to the other few pupusa restaurants I've tried around the city, these were the most stuffed and cheesiest. I ordered the cheese & beans and the cheese & potatoes. While the salsa was quite bland, the lack of taste in sauce was dully noted, as the flavor was all in the pupusas. Plus there's some Tapatio on every table. Splash that on and pile on the cutido (pickled cabbage and carrots)!
You really can't go wrong for $1.75 ($2.25 - $2.50 for meats) a pupusa. I think larger orders get free chips & salsa too, but a few pupusas really filled me up.
Bring your hunger and cash.
Bonus that it's right across from UNLV- but that probably won't mean well for me or my pants size.
