walkahead, yeah, I grew up in Thamel.  And the gullis of Jyatha was where we had numerous beef with outsiders who dared trespass into Thamel (heard the whole mentality has changed now...outsiders walk in and around Tahmel like they own it).  However, jyatha is a derogatory remark that was hurled by all I knew right from Jyatha Tol to the hills of Darjeeling!
