Pasar Badung (Badung Market) is a landmark in Bali. It's half of a market complex. This half of it has the fruits, vegetables, meat and other edible bits of a market place where everything you'd want is for sale.
It also has the best flower petal collection I've seen. The petals come in sackfuls and you can buy them by bunches or bags.
It also happens to be a great place to people-watch. =)
