About our next favorite thing after real estate: Food! And what's the best Mexican restaurant in the SFV?

Are you thinking about food when you're not thinking about Southern California real estate?  Today's L.A. Times Food section has a great article about the best smaller, ethnic food places in the L.A. area.  Note how many are in the San Fernando Valley!  Title should link; if not, click here.

Along these lines, does anybody know of a really good Mexican food place in the east SFV besides Don Cuco's and Mucho Mas?  We went to El Cholo in Pasadena the other day but it has become very corporate.
