Que onda is my favorite Mexican spot Uptown. The food is delicious and the atmosphere is very fun. I have had issues with lunch there in the past (being too long and having to get our food to go), but recently they have stepped up their game significantly.
I highly recommend their dip trio as well as their tacos. You can also get the tacos on lettuce wraps for an additional $1 which seems very reasonable to me. We will be back again soon!
