One of the tasteful little cafés on Istanbul’s small streets, this one’s more an alcove really, off Istiklal Caddesi, towards the Tünel end, Carnival is bright and light and around lunchtime its counter is packed with delicious and generally healthy fare of the pasta, salads and tortilla variety. rnrnBreakfasts are good too and this is one of the nicer places to have a break while trawling down the shopping mecca of Istiklal Caddesi.
