Rim Khob Fa Books (ร้านหนังสือริมขอบฟ้า), 78/1 Ratchadamoen Klang Rd (at the Democracy Monument roundabout), ☎ +66 2 662-3510 (rimkhobfa@yahoo.com). 10:00–19:00 daily. This is a big and upscale shop that looks a lot more professional than the other book shops around Khao San Road. Most of its customers are Thai students who come for the large stock of English-language academic books on languages, arts, and history. But they also have plenty of general-interest books, such as travel guides and cultural books.
