Title:
Kathmandu

Context:
The neighbourhood of Thamel is Kathmandu's primary "traveller's ghetto", packed with guest houses, restaurants, shops, and bookstores, catering to tourists. Another neighbourhood of growing popularity is Jhamel, a name for Jhamsikhel coined to rhyme with Thamel. Jhochhen Tol, also known as Freak Street, is Kathmandu's original traveler's haunt, made popular by the hippies of the 1960s and 1970s; it remains a popular alternative to Thamel. Asan is a bazaar and ceremonial square on the old trade route to Tibet, and provides a fine example of a traditional neighbourhood.
