I swear, in the last 6 months the number of taquerias has more than doubled along Fourth Plain in Vancouver between I-5 and 205. This is becoming a great stretch. Several of the places make a point of offering freshly made tortillas.
One of the newest is Taqueria Colima, which I tried for the first time tonight. I had a taco de asada and a taco de birria. Both carnes were flavorful and cooked nicely. The tortillas were made fresh. They had a red and a green salsa, both good enough. Other meats included adovada, lengua, and pollo. Notably, no carnitas or al pastor, which I actually respect, since too often al pastor is just adovada and carnitas is just roast pork. If they're not going to do it right, they shouldn't do it at all.
Stopped by Poncho's al Pastor and talked with the lady there. They do indeed have the spit turning with the pineapple on top every day. Plus they use an entire pineapple in making the marinade. They grill up the pastor with onions which get nice and caramelly. Their asada is quite good as well. You pay an extra 25 cents for fresh tortillas and you do have to ask for them. The older lady here is very nice and happy to answer any questions and accomodate any requests. She'll make fresh quesadillas Mexico style if you ask, for example.
That makes four really good taqueria options within a mile or so along Fourth Plain: La Michoacana, de Leon, Poncho's, and Colima. There's a new place that just opened that I haven't tried, too. Plus there are at least 4 mediocre options along here.
