Turkuaz hidden up an alleyway just off Istiklal, Istanbul's main thoroughfare, Turkuaz is a bookshop for those who come to Istanbul in search of early editions of novels by Pierre Loti or history books by Tamara Talbot-Rice. A heaven for bibliophiles, a single small room is usually filled with cigarette smoke billowing from the general direction of the owners, who glower at customers from behind piles of books in Turkish, English, French and German. Concentrating on Orientalist literature and the history of the region, expect to leave with an early French guide to Constantinople under one arm, and an introduction to Seljuk architecture under the other.
