İbrahim Yambol and Kazım Çelik ran the bar themselves at No. 41 on Yıldız Caddesi, then renamed it Deal Coffee Roasters and began roasting their own beans. The list leans on experimental Colombian lots and Ethiopian naturals, and a La Divisa natural from Diofanor Ruiz is sold as the 2025 AeroPress championship coffee.
Branches followed in Levent and, in 2026, Nişantaşı, where Deal Reserve pours selected lots across several brew methods. A fourth shop is due in Ataköy.
