The Arizona Center's Starbucks always crowded--and with good reason. This quality of the product is always consistent, but what makes this franchise so popular is the courteous & welcoming staff. I wouldn't really consider myself a regular but they always remember my drink order!
My sister & I eat lunch on their patio daily. They have numerous seating options-including cushiony couches--and misters.
I would highly recommend this Starbucks for their exceptional customer service, the atmosphere, and the quality of their coffee.
