For more than 50 years, locals and tuned-in visitors have come to this open-air food court to feast on Thai-Chinese dishes. There are about ten restaurants under the blue tile roof, and a waitress brings a stack of English language menus to the table, so this is a great place for visitors to experience street food without the language barrier. Among the top restaurants is the eponymous Lock Tien, where locals line up for 50 baht bowls of mee nam tom yam kong, a spicy and sour noodle soup with shrimp. Perfect the flavor with a dash of dried chilies or vinegar from the condiments on the table. Pork (moo) satay with a cucumber and onion relish and peanut sauce is popular, too, with 15 sticks costing 70 baht. Look for a woman in the corner making paper-thin sheets of spring roll paper from a springy ball of dough. Those freshly made papers are sold to local restaurants and used in the fresh (not fried) spring rolls with a sweet and sticky tamarind sauce. Finish the meal with brightly colored sweet jellies over crushed iced with a sweet syrup, which the Thais call nam kang sai.
