I have been to a ton of taco joints in Dallas. From trendy tacos to taquierias. My favorite, close, go to tacos are from the chevron @ Greenville and Lovers. It's a pretty sketch neighborhood, so if you're a couple of girls pulling up in your mercedes, you may want to pass. The chicken (and i NEVER get chicken at a tacquieria) is so good. The rest is okay.
Tacos Al Guero over in east of Deep Ellum is also very sketch but very good. The tacos are much smaller than the chevron, but they're good. Their Suadero is excellent, I can eat about 10 of them.
As for trendy, good 2 go is unbeatable. Velvet taco moved into my neighborhood and it's really good, but good 2 go is far better. No others seem to make a mark in my head.
There is this real sketch gas station across from bachman lake that ken rathbun once posted about to go get tacos at, so I did. It's the only place I've been that serves Trompo - spiced pork on a spit. And the trompo delivers. I could drink their orange salsa.
feel free to ask me about tacos anywhere, i'll review if I've had them or I'll go eat them if I haven't - I have a taco problem.
I don't remember seeing a Chevron at Greenville and Lovers unless you mean the one in front of the Tom Thumb across from Central Market. I didn't know they serve tacos there.
A big, Plus 1 for Tacos El Guero! My favorite "quick" taco joint.
For excellent tacos from a Trompo, also try El Tizoncito on Forest Lane south of Webbs Chapel or their original location on Illinois Avenue in Oak Cliff.
Also, Plus 1 for "Good 2 Go Taco" on Peavy Road near Garland Road. Really great "gringo" tacos.
A couple more (really good) taco joints for you....
Taqueria El Paisanita on Inwood road just north of Maple. It's the little blue and white stand (with seating, now) in front of the strip shopping center there.
And by all means, Taqueria El Si Hay (in your car seating) on Davis Street across from Bolsa in Oak Cliff.
And one of the very best...Taquerias El Fuego on Plano Road just south of Campbell in Richardson. Real mom 'n pop inside sit down taqueria. Great selection of homemade salsa.
I tried the newly opened Velvet Taco at Henderson and 75 tonight. Really, really good, unusual (gringo) tacos. I had the cornmeal fried oyster tacos in a delicate semi-hard corn taco shell with all the "trimmings" and a raw "poky tuna" taco with all the trimmings heavily wrapped in a lettuce taco "shell" ala In-N-Out's "protein burger". Both were excellent and very reasonably priced at $4.50 each. Excellent selection of lesser known "boutique" sodas, too. I will return!
