We are working to establish an Arsenal Supporters Club in Turkey. As the first step we started gatherings to watch the Arsenal games with a group of 20+ fans.
After searching for a pub with big screens, a good selection of beers and decent food we decided on Millwall. Millwall offers decent pub food, and a good variety of beers for a reasonable price.
The decor, ambiance and selection of beers is close to what you can find in the UK. The biggest advantage is the location, just in the middle of Kadikoy and across Kadikoy Pier. So just a 25 min pleasant ferry ride from Besiktas. Kadiköy is the meeting point of the young population on the Asian side. This area is full of music stores, bars, live music venues and variety of restaurants.
The owner is a football fan and you will enjoy talking to him.
