It's that dreaded time of year again when relatives come to visit, expecting a culinary cornucopia of California treats. They live in the boonies and love spicy food. Mexican, Indian, anything Asian, or anything unusual. (They loved Picanha on their last trip.) THE PROBLEM IS... they stay in the San Fernando Valley and there are children who cannot travel long distances. I may be able to sneak them into Hollywood (no Hollywood recommendations, please I've got that covered.) But the valley! From Burbank to Encino -- any thoughts? Anyone? Please?
