Though Muslim Street is regarded as a tourist scenic spot by foreigners, it’s actually considered a snack street by the locals, and is an ideal place for locals to kill time during a hot summer. As a matter of fact, what makes this Muslim Street a food street is unending lines of various restaurants and food stalls, some of which specialize in selling cakes, others in dried fruit or breads, and hordes of stalls selling barbequed meats on skewers.
