Best Taqueria Dallas 2012 - La Nueva Fresh & Hot
Bring a fan, a cooler filled with 10 pounds of ice and a gallon of water. When it's cold outside, it's hot in La Nueva Fresh & Hot, and when it's hot outside, the small Webb Chapel tortilla factory and taquería is roughly the temperature of the surface of the sun. The air conditioning is dodgy here, but it's the tortilla-making machine that causes the real heat. The massive, squeaking twittering machine turns out hundreds of pounds worth of corn tortillas at a time all while belching heat out into the small swampy storefront. Tortillas don't get any fresher, and La Nueva's are soft, pliable and almost as light as air. Order yours with the guisado verde and sample a variety of salsas on the counter while you wait for your tacos. Each is available to take home if you like it, and pounding spicy salsa will help keep your mind off the heat. When you do get your bounty break for your car and crank the A/C. La Neuva is missing tables as badly as climate control but the tacos are worth it. The green pork stew topped with spicy salsa is the best taco available in Dallas.
