Just wanted to say that there is still a Greek market in Rockville. I had thought it had closed, but apparently I kept getting them at the wrong times. They do have Greek yogurt, but only Fage and another Greek brand that is made with sheep's milk. Definitely a fun store to look around, though, and their pastries are delicious.
International Market & Bakery. (301) 424-1844. 10034 Darnestown Rd. Rockville
