My in-laws winter in Mesa, Arizona. We'd like to get them restaurant gift certificates for Christmas presents. Would love your suggestions for Mesa, Tempe, and Scottsdale area (they don't like going into Phoenix). They love SW/Mexican type food, Italian, "meat and potatoes", but no Asian or other ethnic specialties (expect, perhaps, German). They probably wouldn't want a place where you have to get dressed up. Thanks so much! Chowhounds are wonderful!
