Since I wrote my original review, I've been back to Canteen a few times. I've never had to wait for a table, which makes it more of a go-to spot for me. My boyfriend and I like to get late dinner here before going out to the bars. The service can be hit-or-miss but generally good.
The "Duritos" get better each time I go, with a little more flavor, but I still find it to be a weird choice and prefer their chips and salsa (which, I found out, you can order even though it's not on the menu!)
The tacos continue to be decent and filling. I never need more than one margarita to get buzzed. If I could bump up my review a half a star, I might do so. The interior is very intimate and casual.
