Editor’s note: This post is the first installment of “Best Bites of 2012,” a roundup of our top culinary experiences over the last year. 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.

Mexico City is probably not the first place one thinks of when it comes to ice cream. Enchiladas and tacos, sure, but ice cream? In fact, the city has quite an established ice cream scene, with spots in nearly every neighborhood. La Especial de París, an ice cream parlor on the edge of Colonia San Rafael, stands out as a family-owned venue that – unlike many of its competitors, which have increasingly turned to selling mass-produced dairy products – still makes all its ice cream the old-fashioned way, by hand and with fresh, all-natural ingredients.

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?

If Lades, which means “wishbone” in Turkish, provided an actual wishbone alongside the usual post-meal wet wipe and toothpick, we’d close our eyes and make a wish that we could eat their tandır, or oven-roasted baby lamb, seven days a week. These large knots of tender, fragrant meat lined with a soft cushion of fat are the sort of high-calorie lunch that we might save for a special occasion, but Lades regulars take for granted.

While Athens’ more upscale neighborhoods have recently rediscovered the gastronomic joys – and, let’s face it, the economic sense – of eating souvlaki, this classic dish has never gone out of fashion in Athens’ downtown. The city’s longtime souvlaki venues may have changed little in the last 50 years, but there is something particularly satisfying about their old-fashioned, no-frills approach. With their clientele of seasoned fanatics, the best of the bunch offer a lesson in what it truly means to eat like an Athenian. (Keep in mind that the menus at these old-school souvlaki places have remained virtually unchanged for decades, meaning that there is no chicken served, only the traditional pork or “kebab” – usually made with a mixture of minced veal, lamb and sometimes pork – in variations described in our Athenian souvlaki primer.)

We would have liked to like the profiterol at İnci Pastanesi, and to believe their claim that the profiterole was invented on the premises in the 1940s. But in fact, we’ve always appreciated İnci for non-culinary reasons. Until last week, this old-school Beyoğlu pastry shop had been spooning out cream puffs covered in chocolate goop for almost 70 years with respect for tradition and a refreshing contempt for the latest trends in interior design. Our eyes had grown used to resting on its charmingly worn façade as we walked down İstiklal Caddesi. For better or worse, İnci was an institution.

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.

In Mexico, sandwiches generally come in the form of the torta, usually made out of a white bread roll known as a bolillo that has been sliced in half and then filled to the brim with meat, avocado, tomato, onion and sliced jalapeño peppers. In Mexico City’s San Rafael neighborhood, however, a family-owned sandwich shop called La Vaca de Muchos Colores is doing its best to expand the city’s sandwich scene.

From a country that maintains a “national strategic pork reserve” – vast bunkers of frozen meat that can be released when the price of the commodity gets too high – one might not expect to find an impressive number of traditional vegetarian restaurants, but you’d be surprised. While exact numbers are hard to pin down in China, it is thought that around 20 percent of the Chinese consider themselves Buddhist, a number that tops out at around 280 million people. In culinary terms, that translates to hundreds of millions of would-be vegetarians – though, as in any religion, devotees interpret tenets at will, and most “vegetarians” in China enjoy a sprinkling of pork in their tofu to “add flavor.”

It is hard to identify exactly when the forgotten neck of Istanbul between Etiler and Arnavutköy became prime real estate. Not so long ago, overgrown green space alongside the road was interrupted by the occasional car wash and low-slung shanty; it was not so much a place as a road to other places. But now it seems this road is going places of its own. A private tennis club with a swimming pool shares a parking lot with Backyard, a café and restaurant with a big grassy yard filled with lounging parents and children wallowing in that rare Istanbul commodity: grass.

To call Tacos & Deli, a one-year-old family-owned spot in the popular nightlife district of Zona Rosa, small would be an understatement. The main dining area contains six little tables, a tiny kitchen, a taco station and a cashier stand, all of which are squeezed into a micro-sized area that in many other restaurants would probably end up being used as a broom closet.

When Yi Sheng Yue Wei opened on Yongkang Lu almost three years ago, its neighbors were pajama-clad retirees, a mahogany furniture workshop and the Shikumen History Museum – which, to be honest, is actually just one history buff’s storied alleyway house. Now the two-block street is one of the most laowai-gentrified in Shanghai, with bars run by French interns, coffee shops stocked with beans from Ethiopia and competing fish-and-chips shops. Rents have skyrocketed, and there’s even talk of transforming the thoroughfare into a pedestrian street. But amongst the hustle, bustle and inebriated foreigners, Yi Sheng Yue Wei remains, loyally serving the same home-style Cantonese food as it did when it first opened.

The perfect burger, or rather the perfect American-style greasy spoon, has long been the holy grail of expats and locals in Athens. There have been a number of places that have gone after the title of the Athenian burger king over the past 30 years, usually in the affluent southern suburb of Glyfada, home to a U.S. military base in the 1980s, but none have had lasting power. The military base has been closed for some time now but the appetite for American diner-style food (the kind popularized in what have traditionally been Greek-owned diners) has not abated in the least. Enter New York Sandwiches, opened less than two years ago near Pyrgos Athinon (pyrgos means “tower”) – the only skyscraper in central Athens – in the busy area of Ambelokipoi. With a menu that includes burgers, bagel sandwiches and Philly cheesesteaks, old-school letter boards hanging above the counter listing what’s on offer, and pictures of New York on the walls, the restaurant works hard to bring a bit of America to the heart of Athens.

We can’t prove it, but we suspect a network of tunnels lies underground in Beyoğlu that connects most of the meyhanes of Asmalımescit and Nevizade Sokak to the same mediocre kitchen, resulting in unexceptional mezes at scores of venues in this dining district. Following a number of tips, our search for a standout meyhane led us to the unassuming Asmalı Cavit on Asmalımescit Caddesi, where we’ve consistently had outstanding food. This traditional meyhane bucks the trend toward mediocrity with subtle but significant tweaks that, for us, make the meal.

There is literally nothing like a bowl of steaming má là tang (麻辣烫) when Shanghai’s wet, cold winter sets in. In English, it translates to “mouth-numbing spicy soup,” and if that weren’t indication enough that it will get your sinuses going, then the fire-engine-red broth certainly is.
