I love food stands and this is a must try place.  The service was great.  It was freezing and windy the night I went, and the nice vendor told his clients to wait in their cars and that he would bring it to us.  You don't have to go to a fancy restaurant to get 5 star service. The food was interesting.  It was my first time having arepas and I got the hot Lengua Arepas (tongue)  and a cold Reina Pepiada (chicken avocado--**their most raved about arepas**).  Get the green chile sauces..it enhances the taste. They both come in the grainy textured corn bun (similar to an english muffin).  The Lengua Arepas is a little messy because of the oiliness of the sauce. I actually liked the Reina Pepiada more because of the fusion of the cilantro, mayo, and avocado marinating the shredded chicken.  You have to at least try it out once.
