These two are my favorite meyhanes in Beyoğlu. I put them together because Yakup is the cousin of Refik. Refik Aslan opened his Meyhane at Tünel Sofyalı Str. in 1954 and still run the place with his son. Refik offers Turkish dishes during lunchtime and serves as meyhane (meze house) at night. One of the oldest and popular meyhane in area and reservation is required for weekend.
Yakup 2 Meyhanesi: Yakup Aslan is serving in his place for 27 years. It is famous for special hot mezes. My favorite meze is Arnavut ciğeri (fried liver). Needless to say, drink Rakı at both of them. On the Istiklal str., closed to Tunnel square, find Asmalı Mescit str. (a narrow street) on your right. Go straight for Yakup 2 or turn left for Refik.
