I tried this place last night, having first noticed it a few nigjts ago. It's on Crain Highway, just south of Eighth Avenue, a few doors down from La Sirenita or Brown's Honda and on the same side of the street.
It's a nice little hole-in the wall Mexican/Salvadoran place. I ate there late, and at the time, it was host to a group of Spanish-speaking workmen who seemed to be having some sort of support group/beef session/social hour - I presume they had eaten before I got there, and they were sitting and talking in very animated fashion in Spanish about something that seemed to be serious.
Everybody (both the staff and the workmen) were very nice, and I didn't get any of the "What are you doing here, this is our place?" vibe that one sometimes gets in ethnic restaurants patronized by largely non-Anglo clientelle.
I had the pork/cheese pupusa appetizeer (with the usual shredded cabbage and red salsa accompaniment) and the chicken tamal, which was notable for a soft, moist consistency almost like a stiff pudding. Both were very good. Not remarkably different from those I've had in any other Salvadoran place, other than the texture of the tamal, but good.
My main course was the beef tripe soup (Sopa Mondongo?), which was a very hearty bowl of very good soup, which included zucchini, potato, onion and a nice beef knuckle (knee?) in addition to ample portion of tripe (which was left in large chunks), with two think Salvadoran-style tortillas on the side. If you are not weirded out by tendon, the joint made for very nice gnawing. While tendon is normally eaten more for "mouth feel" than its own flavor, the tendon surrounding the joint had picked up a nice flavor from long simmering in the soup.
Dessert was a good slice of tres leches cake. Agian, not that much different than any other I've had, but a fine rendition.
In all, this seems to be the sort of place that puts out good, tasty food at a very reasonable price. Nothing truly unique or distinctive, but very capable renditions of the dishes one would expect of a Salvadoran place of this sort, delivered by a pleasant and competent waitress, in a welcoming (if non-descript) atmosphere.
I'd say it's worth checking out if you're in the Brooklyn/Linthicum/Glen Burnie/Pasadena corridor, or if you're passing through the area from elsewhere.
