After a day of hiking at Red Rock Canyon, we were parched and arrived at 3:30. The kitchen was not open until 4:00 but they were nice enough to open the bar so we could have a drink. The two bar tenders were amazingly friendly, and a few glasses of cold water / El Camino margaritas hit the spot.
Dos Caminos has the best Guacamole in Las Vegas, especially with some added jumbo lump crab.
Also recommend the Dos Enchiladas (with Mole Poblano and Tomatillo Verde sauces) and the Chicken Taquitos.
Don't know about the opening week reviews, but today was great.
