Indian and Mexican cuisines have a lot in common. Both are characterized by the layering of flavors through numerous spices and chilies. Both are born of economies where labor has always been cheap. In the U.S., an often-ignorant public expects both to be inexpensive and demands little in the way of refinement. Masala Street (915 Pearl St., Suite B/C) in La Jolla, for many, will be the first glimpse of just how much more Indian cuisine has to give.
