Once tucked away in a back corner of Gyungridan, Don Charly's popularity brought it out of hidden depths and right above Craftworks Taphouse Namsan for all to see. While tacos and burritos may be the most popular menu items at your average Mexican place, Don Charly's is a different story. Here, they boast being one of the most authentic Mex-Mex (as opposed to Ko-Mex or Tex-Mex) restaurants in Seoul. Hesitant to believe? Have a bite of their vegetal tostaditas, a veggie tostada with lettuce, tomato and avocado. It's juicy and flavorful with a kick, just as Mex-Mex should be. Their menu is extensive, offering you everything from sopesitos to tamalitos and totopos, items unfamiliar to your average taco place. And yes, they also have tacos. The interior is colorful and neat, much like the food. Lines out the door have died down a bit since the restaurant's peak and the tacos have lost a little bit of their glamour, but it's still a beaut.
