I'm not sure 7-11 counts as a restaurant.
Well, maybe it does because I see people getting their lunch there all they time. They have deli sandwiches, strange meat products on the grill and of course — Slurpees. 
Every now and then, 7-11 does something that I find truly wonderful — they give free samples. Usually it's of their new disgusting Slurpee flavor, like "cappuccino".
However, on a recent visit I found something I couldn't resist: Candy Cane Hot Chocolate.
Much to my surprise they had free sample cups (about 1oz) to the side. I grabbed one of the wee things and watched the white-hot Candy Cane Chocolate come pouring out of the nozzle. As it bubbled up to the top it spilled and got all over my hands, but I didn't care. I have never seen white hot chocolate before that also happened to be candy cane flavored. my heart was racing.
