Like everyone else, I consistently encounter terrible service here. I'm now 3 for 3 with my drink orders getting messed up. You're better off going to the Starbucks at 7th St and Osborn. It's worth the extra drive- you're going to be waiting in line 10+ minutes here regardless of how busy it is.
Bonus- on my second trip here, the employees were having a fight and screaming at each other. Keep it classy!
