If you want tacos and a quick bite for lunch and you are in the Ryerson or Yonge and Dundas area, Tacos 101 is a good place to go.
The tacos cost $4 each with the exception of the fish taco which cost $4.50. Each taco is double layered so there are two soft corn shells. I ordered the Al Pastor, chicken adobado and the fish. Each taco was packed with ingredients and flavour. I found the pork in the al pastor and chicken in the chicken adobado a bit too dry even with sauce. I would recommend getting the fish taco since I thought this one tasted the best out of the three that I ordered. The beer battered fish had a good crispy crunch to it and it blended well with the cabbage and mayo.
It is a really small place and they only have 4 seats by the window so if you are going at a busy time, you might have to take it to go.
If I'm in the area again, I would definitely come back for the fish taco.
