This location is always busy and unkempt and dirty.  I usually plan to wait for 15 minutes when I go here.  It's also very hard to find, so familiarize yourself with a map (or use google maps every time like I do) \n\nI try to use the location on Scottsdale & Williams as much as possible for an overall better experience.  It's located here:\n\n7339 E Williams Dr\nScottsdale, AZ 85255
