Soi Lalai Sap This is one of Bangkok's most popular lunch-time shopping areas, located next to the Bangkok Bank headquarters on Silom Road. Starting just before noon, and closing not long after lunch breaks on weekdays only, the market is packed with office workers who shop for clothing, leather goods, food, gifts and knick-knacks. It is almost impossible to walk through the tiny alley without spending some money, hence the name "Soi Lalai Sap."
