I wasn't disappointed with the food at Me & Julio, but I wasn't overly impressed either. I had an orange margarita- which was very tasty, and not overly orange-y. We started with the chips and queso/guac, which I also enjoyed. The chips were light and not too salty. However, the queso was lukewarm at best and the guac had started to turn brown. It was half price at happy hour though, so I guess you get what you pay for.
For a meal, I ordered the bang bang shrimp tacos. Again, not bad, but not entirely impressed either. They could really up the flavor if they added more cilantro and bang bang sauce and if they pickled the carrots.
Not sure if I'd come again. I think there are better Mexican food options in Madison.
