I've been here twice now, and haven't been impressed either time. The most recent time was pretty bad, and I would rate the service one star. Our server was MIA for our entire visit. Neither of us got refills on our drinks, she didn't check on us after the food was delivered, and we had to flag her down for the check.
We ordered nachos and they came out dry, with my 6 black beans (I'm not exaggerating),a tablespoon of beef, and a tablespoon of guacamole on a huge pile of oily tortilla chips. $12 for 6 black beans and enough guacamole for 4 chips...so we flagged down the server and asked if they no longer put queso on the chips. She just looked at us. Awkwardly. For a good 10 seconds. I asked again. She pointed to a corner of the plate and said, "there is a little bit right there" and awkwardly looked at us again. I asked for more on the side and she brought it. It was one of the strangest interactions I've ever had with a server.
Our tacos came out and they were mediocre. Nothing that we can't make ourselves at home, and honestly, I wish I did just make them at home.
I'll skip Canteen and head to Tex Tubbs next time.
