Don't go Jakarta, it's like India, Bangkok or Nepal noisy, air pollution and the most I can't stand was the car/bus honking.

Go Bandung, preferable not weekend. Coz weekend is the shopping day for Jakarta people. Is the heaven for shopping. Go with without luggage, buy luggage and clothes in Bandung. You can get Levi's jean around RM60-70, branded luggage less than RM300... Victoria's secret panties less than RM50 LOL LOL
