I really enjoyed Trees Pesos. 1st I'll talk about the food, then I'll talk about the service...
The food - Very good, with the exception of the salsa. As others have stated, it is very thin. It's flavorful, but the texture is lacking and it runs off of the chip when you dip it. Great fajitas at a very reasonable price.
The service - The waitresses are the primary reason I come there. There are a couple girls that are VERY attractive. They have those perfect, curvy Latina bodies. However, they need to smile more. They would be so much prettier and inviting if they smiled a little more and maybe sat down for a second to ask me how my day is going. I myself am very handsome me, so I would think that they would be more interested. Maybe they are shy. In any case, I'm gonna keep working on them and continue to come back :)
EDIT: I guess Yelp didn't like me talking about the hot waitresses. I don't know why. Attractive wait staff is the primary reason I go to restaurants...
