As a child, Manel Palou spent hours playing in the kitchen of Andorra, his parents’ restaurant in Barcelona’s Barrio El Born. Later, as a teenager, he helped out behind the counter while his brother Miki cooked in the kitchen. Originally bought by his grandfather in 1952, the small restaurant had been around for as long as anyone could remember; even the old-timers in the neighborhood can’t remember where the name comes from or who the previous owners were. Then in 2004, Manel’s parents decided to sell Andorra and retire. Within six years, the restaurant went from being a neighborhood favorite to a mediocre Italian joint with few clients and little charm.

At first glance, Restaurant Roma doesn’t appear to be anything out of the ordinary. The nondescript brown tiles covering the floors, the dark wood bar, the vaguely Mediterranean-inspired wall décor and the rectangular paper Ikea lamps are similar to those at hundreds of other midrange restaurants throughout Barcelona. Situated on a quiet street in residential Sant Gervasi, Roma isn’t somewhere you’d be likely to come across accidentally, nor is it the kind of place you’d happen to hear about, unless you (or your aunt, or coworker or a friend of a friend) lived nearby. And that would be a shame because the food at Roma is good – ridiculously delicious, in fact.

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?

One of our favorite markets in Mexico City, Mercado Jamaica is a fantastic destination any time of the year, offering everything from festive Christmas decorations to a large selection of fruits and vegetables. After the markets of Xochimilco, Jamaica is also one of the city’s best flower markets, with block-long aisles filled with freshly cut flowers and plants of almost every imaginable color and type. But as much as we love getting lost in the sweet scents of these green alleyways, what keeps us coming back to Jamaica is El Profe, an excellent eatery inside the market that specializes in barbacoa. El Profe ("The Prof") looks less like your typical market food stand and more like a mini restaurant, with small brass chandeliers hanging from the ceiling that provide more in the way of ambiance than actual light. Waiters and cooks in matching blue uniforms hustle and bustle around the customers, who come and go from the counter at a steady pace.

As the moon starts to wane each January, people throughout China frantically snatch up train and bus tickets, eager to start the return journey to their hometown to celebrate the Lunar New Year (春节, chūnjié) with their family. One of the major draws for migrant workers heading home is the chance to eat traditional, home-cooked meals.

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?

As the legend goes, a 19th-century Catalan farmer was out experimenting in his fields when he came up with a new kind of longer, juicier green onion, the calçot. In creating the onion, the farmer produced much more than a new vegetable; he also paved the way for the rise of an idiosyncratic, and distinctly Catalan, cultural event.

Markets in Mexico City are as integral a part of the culture as mariachi music and tacos, providing a place for neighbors to come together for shopping, gossip and family outings and playing a key role in keeping the social fabric tightly woven. While most neighborhoods have their own brick-and-mortar locations, their street markets are far more colorful. These crowded, boisterous shopping areas – some so large that their colorful tarp roofs can been seen on satellite photographs, stretching for miles – are also an essential component of the city’s culinary scene.

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!).

Editor’s note: This is the penultimate installment of “Best Bites of 2012,” a roundup of our top culinary experiences over the last year. Stay tuned for our final “Best Bites” dispatch, from Istanbul, tomorrow. Restaurant Roma We hadn’t planned on bringing in La Nochevieja at Restaurant Roma, but it was nearby and we didn’t feel up for public-transport adventures on New Year’s Eve. Situated on a quiet street in the upscale but untouristy Barcelona neighborhood of Sant Gervasi, Roma is thoroughly nondescript – a neighborhood joint frequented by neighborhood people of a certain age. The wood-paneled walls, racks of Maxim magazines and TV mounted in the corner kept our expectations pretty low.

Stay tuned throughout this week for “Best Bites” from all of the cities Culinary Backstreets covers. Hai Di Lao Hot Pot Restaurant We’re usually loathe to mention a restaurant that has locations all around China, but we were blown away by the dedication to customer service here – something that is sorely lacking in China. Too often, it’s a choice between authentic flavors or service. Not at Hai Di Lao.

The arrival of fall always finds us heading instinctively, like salmon swimming towards their ancestral headwaters, to the Balık Pazarı, Beyoğlu’s historic fish market. Autumn is quince season in Turkey and that means the appearance – for a limited time only – of one of our favorite desserts, ayva tatlısı (literally meaning “quince dessert,” although “quince in syrup” might be more accurate). Nestled in the fish market is Sakarya Tatlıcısı, a pastry and sweets shop with old-world charm that is one of our top stops for this dessert. The apple-like quince is one of those complicated, mysterious fruits that take on a new life when cooked. Raw, quinces are often astringent and inedible.
