They sell the best pupusas in town and their natural drink are very good. The strange thing is that you have to use the back door and parking because They cancel the door entrance on Holt Ave.......

Don't judge a book by its cover applies here. From the outside you think you may be walking into a rundown facility, but once you get past the fence and into the lobby you see it's a nice little restaurant. We were greeted and seated by our waiter who was above and beyond polite. I had low expectations, but was blown away by the quality of food received. The food was all fresh prepared and you could taste it. The chicken taco was great! The pupusas were also fantastic. The lunch special I ordered also came with an outstanding flan. Not a single complaint to make. The service isn't super fast, but you're getting fresh food which makes up for the wait. I highly recommend finding time to stop here. You will not be disappointed.

Really nice customer service. We felt welcomed/appreciated. They seem to work hard to maintain clean tables and dining areas. I like that their pupusas are Not super oily and the curtido is flavorful without being spicy! We would come more often but they are not open on Sundays : (

The food is great the service amazing and drinks are other worldly exceptional. I am a serious foody am constantly looking for the best foods in my area. I went in and got a plethora of different pupusa types including pumpkin. I also tried the green lemonade, horchata, fruit juice and Jamaica. I said multiple times "this is the best (blank) I've ever had". Can't say enough great things about this place. 10/10 would recommend.

The owners are always very friendly and welcoming. The place is very peaceful and it’s a great place to eat with your family, friends, and or loved ones. Definitely recommend it!

The food was amazing! The owner took our order and explained how they make everything themselves even the drinks. (Besides the normal fountain drinks) He was so friendly and loved explaining how they make their food. I would 100% go again and bring my friends. And there were plenty of veggie choices (which was as enjoyable as all the other food)

Excellent food, of course specializing in pupusas, which are not easy to find. The owners are very nice and attentive. Lots of fresh smoothie flavors too.

One of my favorite spots in Pomona! Best pupusas and horchata — this past week we placed a large order for a group of 20+ people and the folks at Guasalmex were the best! Funny, kind, and super accommodating. Honestly a wonderful experience, and I can’t wait to go back!
