I was not impressed by this coffee shop, even though it had a nice view of the south of Tehran from the Opal's sixth floor. The place was not cozy at all and the furniture was very uncomfortable making it impossible to stay and enjoy. The drinks were expensive and they came in plain paper cups, which was really surprising! Also, one of the staff members, who was from Botswana, did not seem very happy or friendly, even though he was polite. He did not greet me warmly, and he was reluctant to talk.
P.S. One of the founders told me that they had just reopened two days ago after a redesign and that they would improve soon. So I will give them another chance in a few months.
