I come here all the time to eat tacos. I'm mexican and I can say they are the most authentic tacos I've had in Madison! delicious. Although their food is great, I can't say the same for their customer service. No smiles or friendly staff, they can actually be pretty rude. I sometimes shop at the store as well and it's always a bad customer service experience. Mostly all the staff seems annoyed that you're there and can't wait for you to leave. They try to avoid eye contact or speaking. I hope they can improve on their service but I think I'll keep going there to get my taco fix and grocery items.
