@ysmina-- The Greek grocer in my city carries the coffee and I think a couple of brikis as well. If you have any Greek groceries where you live, check there first. The briki options are generally limited in these stores though. You might have better luck if you look for it online. The options and prices are probably going to be better.
If you don't have a Greek grocery, then any International foods store, or Middle Eastern groceries might have it as well.
I know that Arabic coffee (also same as Greek coffee) comes in cardamom flavor. Cardamom is a spice that is used a lot in the region. I don't think Greek coffee has any flavors but I might be wrong.
Does anyone know about Greek coffee flavors?
