We go to Cancun at least once a year and always go to Tacun, one of the best, authentic Mexican restaurants we've come across, with very reasonable prices. I took my daughters there during our girls trip, and it again, it did not disappoint. Two...of us got enchiladas and the other got sopes, all delicious! Drinks were great (one daughter said best Margarita she's had in Cancun), the waitstaff was helpful and attentive, overall it is just a really exceptional place! Warning: it is really a hole-in-the-wall (tiny with limited seating), doesn't take reservations, and is cash only, but really is worth it!! Give it a try, I doubt you'll be disappointed.More
