I started walking down Cihangir Street in search of a place with Wi-Fi and ran into Journey Cafe. Few tables, interesting book selection, crowd is a mix of locals and foreigners, all very enticing.
Although I wasn't hungry I saw plates of very fresh looking mezze and thought that running the Istanbul marathon tomorrow entitled me to a snack! I ordered the Halloumi sandwich with basil pesto, tomatoes, and spinach. Simply put, they blew it out of the water. Perfect texture and balance of flavors, no ingredient overpowered the mix. If you are in the Cihangir come down and water the sandwich down with an apple ginger juice!!
