I've been to La Taqueria a couple of times now because I think they have the best tacos in the city, but they are also the most expensive. The tacos here are tasty two to three bite affairs packed with great Mexican flavour. They've got your standard choices like fish tacos, asada and carnitas. Plus they bring something different to the table with beef cheeks, beef tongue, and chicken in a chocolate mole sauce.
You order your food from the friendly server at the counter, and a waitress will quickly track you down to deliver your food. There are a variety of sauces and pickles that you can help yourself too. The tacos here are simple and really let the main meat ingredient shine. The restaurant is small, clean and smells delicious. The walls are adorned with pop bottles and there is pretty good music playing. They have an open kitchen which lets you see your food being prepared. This place is packed if you come at lunch time, and you'll probably have to wait in line to order for 10 - 20 minutes.
My only gripe with this place is the price. They have four tacos for $9.50, but keep in mind that these things are tiny. Too me, the four tacos here are just a snack. That's really all I'm looking for in a taco though as I don't think that they alone should make up a meal. Although, there are certainly worse deals to be had around the city.
I recommend this place for the excellent tacos, but some people may feel they are getting a pricey snack, so don't have the expectation when coming here that you will get a filling meal.
