Only two decent places for a cafe latte or capucino.
Morning Star cafe - Good coffee, surprisingly good pastries and always a few expats. My favorite place for a egg and cheese croisant on a Saturday morning
Cafe Sigafredo's - London, Paris, Miami and yes - Dushanbe
You'd swear you weren't in Tajikistan. Decent Pasta, good coffee, and great french fries. It's the little things...Lot's of expats as well. I take visitors here and don't have to cringe.
The Hyatt on Saturday or Sunday mornings. Pricey but worth it every now and then.
