I haven't eaten there, but I drive past all the time. Certainly looks authentic; I doubt you'd find much English spoken in there. The village of Farmingdale has lots of Salvadoran immigrants, who I suspect make up a big part of the clientele, so I'd definitely expect some authentic Central American food.
I'll try to give it a shot sometime soon and report back.
Let me know, there is an english menu at allmenus I found a blogger who was writing about a whole bunch of places on LI I had never heard of in Eastern Nassau/Western Suffolk (Plainview, Hickville, Massapequa, Huntington, Farmingdale) Sadly he moved to Queens He has over 100 reviews on Yelp too.
Hey, I did move to Woodside BUT I still work in melville - which is right in the center of it all. I am realizing now that this area is actually very special. Jackson heights has a lot of columbian/mexican but the food in farmingdale and huntington is as good as anywhere I've ever been.
As for el paso grill, they can be hit or miss. They were probably the first place I went to when I started discovering all of these pupuserias. They got new owners within the past 6 months I believe. They are pretty good though. On sundays they have this seafood chowder soup that's excellent.
Nelsons down the block - which looks like a deli - has excellent food. The deli next door is good, but probably better during lunch - when I go after 6pm, things are usually getting stale from the heatlamps.
Lately, I have been going to huntington station. Cardiolos pupuseria and la bodega hispana are excellent. Cardiolos has this pan con pollo (chicken sandwich) for 3.50 which is crazy - probably would be famous if enough of the general public knew about it.
Thanks for the shoutout, do I know you mrPhil? are you on yelp?
