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.

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?

Dear Culinary Backstreets, I’ve been hearing a lot about shark fin soup in the news lately, from countries banning the dish to people protesting government intervention. What’s all the fuss about? Imagine a wedding without Champagne. No popping corks, no celebratory toasts, no drunkenly giddy bridesmaids. Sounds like a nightmare, right? Shark fin soup is the Chinese equivalent of bubbly – only fermenting grapes has little effect on the environment, while the practice of “finning” has seriously jeopardized the survival of some species of this ancient fish. To harvest the goods, fisherman chop off a shark’s fins, then dump the still-living creature back into the water. Without its fins, the shark cannot swim and either sinks to the bottom of the ocean, where it drowns, or is eaten alive by other predators.

Dear Culinary Backstreets, I heard that the Monday on which Lent begins is a holiday in Greece and that there are some special culinary traditions. Is this true? What do Greeks eat on this day?

Dear Culinary Backstreets, I’m traveling to Barcelona and I love visiting food markets. I’ve heard a lot about La Boquería, but are there any other markets that might be worth visiting?

Dear Culinary Backstreets, I keep hearing about Greek coffee but is it any different from Turkish coffee? And do most Greeks actually drink Greek coffee these days or do they drink other types of coffee? Greek coffee is exactly the same as Turkish coffee – and it was in fact called just that in Greece until Turkey invaded Cyprus in 1974, at which point, for political reasons, the Greeks decided to rename their coffee “Greek coffee.” The process and preparation, though, are identical to the Turkish way.

Dear Culinary Backstreets, We’ll be visiting Mexico City and are wondering about the organic food scene. Will it be easy for us to find organic produce? How can we know whether or not something we’re buying is really organic?

Dear Culinary Backstreets, In just about every restaurant or bar I’ve been to in Barcelona, I’ve seen a dish called “tortilla.” What exactly is a tortilla and can you recommend any places where they are done especially well? Although it would seem that much of the world imagines the inhabitants of Spain subsisting largely on paella, the truth of the matter is that it is the tortilla española, also known as tortilla de patatas (truita de patata in Catalan), that  really holds the place of honor in the hearts and stomachs of Spaniards. Often translated into English on menus as “potato omelet,” this hearty round cake of potatoes, eggs, olive oil and salt has nothing to do with the traditional French omelet, nor does it have anything in common with a Mexican tortilla. At its most basic, the Spanish tortilla is made by frying up a thick mass of sliced potatoes and eggs in olive oil and then slicing it into savory wedges.

Dear Culinary Backstreets, I’ll have an eight-hour layover in Istanbul and was wondering if you have any suggestions for places to go for a good Turkish breakfast and lunch. I love to eat at small, local places serving authentic food. I would prefer restaurants in the Yeşilköy area, as I have to be back at Atatürk Airport to board an international flight (which I cannot afford to miss!).

Dear Culinary Backstreets, What and where is safe to eat in Mexico City? We’ve heard horror stories from other travelers about “Montezuma’s Revenge” and would like to avoid getting sick while visiting the city.
