Mixteca is one of the many Mexican restaurants in Phoenix that has Ceviche...a food that has fish, shrimp and some other varieties of seafood "cooked" by lime juice with a small amount of tomatoes and onions. The kind I typically have is with shrimp. You can get a good size cup (20 oz?) filled to the brim with it along with tostadas for $11. Yes, it sounds like a lot but it's worth paying for it if you don't know how to make it or don't have the time to make it.
