I am so sad there isn't one here in Tucson.
I was going through Tempe and a few friends talk about them lots, so I thought I'd stop by. The line was 15 cars long. A good sign, but I wasn't sure I wanted to wait. But I pulled in and a person took my order via a phone outside.
tip - look at the menu online before you go. They took my order well before I got to the menu board, and it didn't even list anything other than the monthly specials.
They are decently priced, less than Starbs. Their large is 30 ounces (or close to that). I got an iced amaretto mocha, and oh my gosh! I want that everyday! Wasn't super sweet, I could actually taste the amaretto. That line moved fast. The cashier was great, told me about double stamp day.
They only franchise to employees, which is awesome, but sad for me. Come to Tucson!
