Dear Culinary Backstreets, Where can I go in Barcelona when I'm tired of sightseeing and I just want to sit down and relax with a cup of coffee? Visiting museums and landmarks can be a lot of fun when you're a tourist but sometimes you can learn more about the life of a city by sitting in a chair in a café than you can by reading any guidebook. In Barcelona, there's no shortage of cafés but like anywhere else, it can sometimes be a bit tricky to find one that has just the right ambiance.

Editor’s note: This feature from Barcelona is the third installment in our series this week devoted to the top street foods in each of the Culinary Backstreets cities. In Barcelona, a great deal of eating is done in the streets. Sidewalk cafés line the plazas and paseos, often to the point that it’s difficult to tell which tables belong to which establishment.

Dear Culinary Backstreets, We will be visiting Barcelona with our children. Do you have any good recommendations of places in the city to eat with kids?

While the Princes’ Islands make for a great escape from the city, it used to be hard to think of them as a culinary destination. That is, until Heyamola Ada Lokantası opened. The restaurant is a perfect storm of inspired food, chill ambiance and small-label Turkish wines, all at ridiculously low prices.

Dear Culinary Backstreets, I hear that Spaniards take their dinner very late. Are there any good restaurants in Barcelona that start serving dinner before 9 p.m.? Indeed, Spaniards are notorious for eating late. Even when dining at home, the typical Spanish family doesn’t eat their dinner until around 9 or 10 p.m. – or sometimes even later! The main reason for this is that for most people in Spain, lunch – which usually consists of at least two courses and is eaten at some point between 1:30 and 4 p.m. – is the most substantial meal of the day. It makes sense, then, that nobody has much of an appetite again until late in the evening.

Dear Culinary Backstreets, I’ll be in Spain during the December holidays and I’m wondering if Barcelonans eat any special meal on Christmas? If so, what is it and where in the city could I try it?

Diners in Istanbul are spoiled with options for fresh seafood. But most venues are mere caricatures of places like İsmet Baba, where traditions have been kept sacred for more than 50 years. While many other such restaurants are kitschy, İsmet is gritty and authentic. Located in Kuzguncuk, a charming neighborhood on the Asian side of the Bosphorus, it may not be the best restaurant in the city, but it’s got something most of the others have lost: old-school Istanbul charm and character.

Be it kvass in Russia or boza in Turkey, every nation seems to have one of their own, a locally loved drink that to most outsiders comes off as a particularly strange brew. In Spain, that drink is horchata, a unique and deliciously refreshing concoction made from chufas (tigernuts), water and sugar. Served chilled, horchata is beloved all over the peninsula.

Like Atatürk statues and crescent-and-star flags etched into the sides of mountains, the öğretmenevi (“teacher’s house”) is an integral part of the Turkish landscape. Found in almost every city in Turkey, these government-run institutions serve as affordable guesthouses for educators on the road and – since anyone is welcome if space is available – for those traveling on a teacher’s budget.
