El Buen Gusto, 360 N. Park Ave. (at Center), Pomona; open daily, 10:15 a.m. to 7 p.m.; cash only; second location at 990 E. Holt (at Reservoir)

Reader Helen Uceda recommended El Buen Gusto to me possibly three years ago (ulp), seconded by a friend of mine, and the restaurant was dutifully added to my list of places to try around the region. Time passed, as it does, until recently I scanned the list and I made a point of finding the restaurant, which I didn’t believe I had ever noticed despite it being on the fringes of downtown Pomona.

But there it was when I looked for it, in a nondescript building alongside a barber and a botanica with its own tarot reader. I parked around the corner and stepped inside for a late lunch.

Even after 3 p.m., there were a few customers inside the modest restaurant. You order in the lobby at the window, where they also dispense takeout orders. I asked the employee, who might have been an owner, what people ordered, and she listed a few items — pupusas, fajitas and beef soup are the ones I recall — while saying the pork, cheese and bean pupusas were the most popular.

I got two of those — they’re known as revueltas — and a guanabana agua fresca. She said I could pay upon leaving.

There are two small adjoining dining rooms, probably evidence the restaurant has expanded into the next door space. An El Salvador flag is displayed in one window. A Spanish-language program played silently on a TV. After a while my food was delivered: a plate of two thick, pancake-like pupusas, plus a bowl of a vinegary slaw to use as topping.

I’ve had pupusas a handful of times. These might be my favorite, stuffed, delicious and filling. The guanabana drink was sweet but light, a good combination.

The bill: $8. That’s hard to beat.

El Buen Gusto may not be much to look at, but the food is good and the staff polite. I should have tried them three years ago.
