Starbucks around here have racks for the most part. If you ride up thru the drive-thru they refuse to serve you. (I've tried it, they say you are a hazard... Hmmmm... and they aren't allowed by company policy to serve bikes in the drive-up.)

I tend to prefer independent espresso stands who WILL serve me at the window or coffee shops that let me bring my bike in (Yay, Diva Espresso!). But if I were to need a lock, I'd use my On Guard u-lock with cable.

Used it with just the u-lock part at the beer garden for Oktoberfest.
