If u come to JB and ask me the interesting places for outing at night, i'll suggest you to go to Tasek Merdeka where you can enjoy the musical fountain.
The fountain goes along with the music played there..
I went there last few weeks with my family and really enjoyed the music and the animated fountain..
Then, we went to the city to enjoy the colourful neon lamps that were hung all over the streets and trees..
The city of JB is very bright at night..
I could even enjoy the beautiful lights although i was in the car!
There is a downtown which we call 'pasar/bazar karat' nearby. You can get some quality items with a reasonable price.
So,, Welcome to Johor!
