The majority of Houston's mobile food vendors purvey Mexican food, hence the common name Taco Trucks. Okay, there are numerous bbq wagons or trucks, a few Cajun, a few shaved ice, but mostly it's tacos, tortas, quesadillas, etc.
Then there are a handful of vendors offering the cuisines of other nations. Here's a list of the ones I've encountered or heard about with international fare.
The Rice Box Truck
Cholaos Kitchen - a Colombian/Mexican truck
Perrida de Mao - I've just seen this one parked (at a repair shop), not in operation, but from the name and the pictures on the side, it's a Colombian hot dog cart.
Los Perros, Houston - this one operates in a strip center parking lot at 9411 Richmond and serves hot dogs and kabobs according to a guy I talked to once. It's open only in the evenings.
FRENCH - L'es-Car-Go - review here. .
GUATEMALAN - see a separate report here.
Abu Omar - Hillcroft @ Pagewood, Mexican menu during the day, Middle Eastern menu in the evening.
Antojitos Hondurenos - 7171 Fondren, just north of 59, and 9713 Airline - the Fondren location has been reviewed on this blog.
Comida Tipica Hondurena El Caracol - first seen on Beechnut at Club Creek but now parked on Bissonnet @ Hillcroft. A smaller bus than any of the other Honduran mobile units I've seen but what looks like a larger menu, reviewed here.
Jennifer's Food - Comida Hondurena - a truck spotted rumbling down Bissonnet but location of operation not known.
La Polera Colora - 2435 Wayside, just NE of 45, noted by Alison Cook in the Chronicle but I haven’t checked it out. As Alison noted, from the name it was apparently at one time a Colombian vendor. I have made several trips and never found this truck.
Sabor Catracho - a big bus, similar in appearance to the Antojitos Hondurenas bus, one block east of 59 on Bellaire.
Ashka's Dhaba - Beechnut, just east of Highway 6 - originally located in the Heights, this trailer has relocated to the far west side, outside the city limits. Far back from the street it's easy to miss though there is a big street-side sign. It is open 7 days, evenings only. There are covered tables.
Bansuri Indian Food Corner - Wilcrest, just north of W. Bellfort, vegetarian street food of Mumbai, reviewed on this blog.
Tandoori Nite, 7821 Hwy 6 South, Sugar Land, at a 66 Station, 7130-852-7642; open evenings, 5pm - Mid except Tuesdays, reviewed here.
Desi Grill and More - an Indian truck serving tandoori chicken and the like at 12672 Veterans Memorial Drive near Bammel-North Houston at a Valero station.
Wally Wally - Indian street food for the streets of Houston. Facebook, Twitter.
There is a Nigerian food truck at Bush Intercontinental reportedly that sells mostly to cab drivers.
El Mofongo Boricua - 1925 Hwy 6 S, by the Mayflower Center (about 1/2 mile south of Briar Forest). Reviewed on this blog.
Pupuceria Ramirez - Salvadoran - S. Post Oak, just north of W. Orem, mentioned in Quick Bites IV on this blog. but missing from that location for some time.
Taqueria y Pupuseria Esmerelda - See for a long time on Highway 6 @ Bissonnet @ a 66 Station, Sugar Land, but recently missing. They advertised tamales on weekends.
Taqueria y Pupuseria El Invasor, formerly found on Bissonnet but current location unknown. Reviewed on this blog.
I have seen numerous other taco trucks around that also serve pupusas but they usually don't have 'pupuseria' in the name.
The Pad Thai Box
Arepas y Empanadas Dona Maria - 1960B east in Humble. UPDATE: The cart is no longer in operation but there is now a restaurant at 1315 E. 1st Street.
El Punto Criollo - now located next to the parking lot for World Foods, on Beechnut, just west of Highway 6. A table and awning are also provided for customers now; reviewed here.
Sabor Venezolano - parked in a filling station driveway at Crossview and Westheimer, one block east of Fondren (713-780-2663). According to their card there is another unit at 5130 Hwy 6 N (281-859-2324). I've never checked that one out but did happen across another unit on Fry Road in Katy, about a half mile north of I-10, in the parking lot of a Gulf station. Arepas, Cachapas, Empanadas, Patacones, Pastelitos, Tequenos, Pabellon, Venezuelan hot dogs and hamburguesas, Pepitos, Tacos, Quesadillas, Burritos and Tortas are listed on the business card which also says they're open til 4:30am Friday and Saturday.
On a visit a couple of years ago I had the Patacones here, a Carne Mechada (shredded beef) sandwich using mashed, fried slices of plantain instead of bread. It was no where near as good as the one I had had at the short-lived Pana's Cafe on Scarsdale. More recently I tried the Venezuelan hot dog here and an empanada carne mechada. Houston is not a town for great hot dogs and this one did nothing to change my view on that; the empanada unfortunately was made ahead of time and had been sitting in a glass case but the filling was very good, rivaling the best empanadas at the Original Marini's.
On another visit I had the Empanada Pabellon with carne mechada and black beans and an Arepa Pelua with more of the carne mechada and queso amarillo. The empanada in this case was much fresher and warmer and also included some plantain. The arepa was freshly made; apparently I could have asked for a different cheese. The arepa itself was very tough.
Givral's Vietnamese Cafe, located on Bellaire in New China Town, has launched a Banh Mi truck that appears regularly at Jones Plaza. Keep up with the schedule on Facebook.
And Les Givral's Kahve has the BanhMieria.
Phamily Bites - pho cups, banh mi, Vietnamese egg rolls, etc. Picture here.
