I tried the Dos Caminos in Midtown recently, and found it good but not great. The guacamole, for which it is rightly lauded, is excellent and addictive. My huevos rancheros, though, were a little too heavy, and globbed on egg on cheese in a heavy-handed way. I'm not saying that the final result wasn't tasty, but it wasn't inventive or too visually appealing. In addition, the normal ranchero sauce includes bacon, so the substitute was a salsa verde that was probably not as good. In fact, only the salsa verde is vegetarian: both the ranchero and the mole have some kind of meat stock. So that's disappointing.
Otherwise, the Dos Caminos ambience is nice, especially if you can sit outside. Service was relatively prompt.
