I've driven past Joe's a dozen or more times but never went.
A couple weekends ago I went with my 12 year old and I think she liked it as much as I did.
It's a cute little place with plenty of places to sit outside in the great AZ weather. The temp and blue skies were perfect the day we went.
Even though the wait was long it was well worth it. We sat out back under one of the gigantic trees while we waited. It smelled like a weekend barbecue and it was actually quite relaxing.
We split a burger and fries which was the perfect amount for us. My daughter got a chocolate shake that was absolutely yummy and I got the ginger ale made with real cane sugar. It is such a refreshing change from the sugary sweet sodas.
I think the price was a little high but I would rather pay more for good quality food than buy something off the dollar menu these days.
