This review is just for Canteen's happy hour - apart from the complimentary duritos that they serve, I've not had their food.
My coworker and I have been steadily working our way through different happy hours in the Madison area and Canteen has become a favorite of ours because of the strong half-priced margs they serve. Their house marg is 7 bucks usually so during happy hour it's a dangerous $3.5!! The first time we stopped in, we were greeted by the manager. It was pretty empty when we walked in at 3 and the manager was very friendly and nice and made pleasant small talk with us - not the kind that you're trying to get out of but the kind that you don't mind because the person you're talking to is so nice! He brought us our bag of duritos promptly, explained their origin, and when we ordered our drinks, he was sure to ask if we wanted salt on the rim. I got the strawberry margarita and my friend got the house margarita and we were both very pleased with our drinks - they came out promptly and were tasty and strong.
The second time, we were greeted not by the manager but another worker and our service was a little less excellent. We ordered the same thing but he didn't bring out duritos - we had to ask - and my friend's drink came with salt on the rim, which she did not want. Pretty minor things but it made us miss the manager! Also, we were a little confused because he put the duritos on the bill, even though the menu states that the first bag is free. It's only a dollar so we didn't bring it up but it was just a bit inconsistent with the service we'd previously received. We'll still be back though because they have good margs and the happy hour drinks deal is super solid.
