Anybody have protein drinks on their menu?

[bamaster]

There are a couple coffee shops here in Houston that offer "power drinks" similar to that of Smoothie King. Protein based frozen drinks, usually with a ton of flavored syrups and fruit. These are a dollar or two more than a latte and seem to be more popular than I'd expect.

I suppose it's clientele specific. Maybe if it was located next to a gym it would be expected.

What about you guys?
