Las Vegas needed a Tex Mex place. Being from Houston we couldn't believe that there wasn't a single true Tex mex in the entire city and have looked for 12 years. Los Cucos is from Houston (I believe as they are all over town). FINALLY I can get a real fajita in LV. In Houston I would rate Los Cucos as a slightly above average Tex Mex but I am so happy to have it in LV and being it is the only one here I give it 5 stars! THe service is excellent and the restaurant is exceptionally clean (it is brand new). They have a Sunday brunch that is pretty good. I love their chips and green salsa and the Fajitas are amazing. Don't go here looking for northern Mexican style food (Michoacán ) like u get everywhere else in town- THIS IS TRUE TEX MEX
