The the streets on the island of Bali in Indonesia are rather amazing. A contradicting yet some how functional mosaic of temples (Balinese Hindu), tacky souviner shops, bars, resturants, massage parlors, internet cafes, etc. all spilling into a 20 ft wide alley (street) that is already full of taxis, motorbikes, donkey carts and peds. Poppies Lane 1 & 2 in Kuta Beach are probably the most intense and fun (or annoying depending on your mood and schedule). the markets and royal palace in city of Ubud are amazing as well. Especially once the dance performances get going at night.
