Route 66 is a Bangkok institution, perhaps even more fabled now that its rival, the neighboring Slims/Flix has closed. Open over 20 years now, Route 66 is famed for huge parties. It's the scene of the Thai youth movement, with thousands of university kids heading here nightly. There are four immense dance zones, that feature everything from live bands playing Thai pop to hip hop to house, and there is also a large open-air space to party at. You'll also get to experience traditional Thai partying here, where groups share a bottle of whiskey, congregate around a table, and drink and dance right where they are seated. It's far more of a group spot than couples, but if you offer a toast, you'll most likely make friends pretty easily.
