Johor Barhu, is a quickly growing city at the border with Singapore. The historical center is little and not particularly interesting, people come here mainly for busines, do shopping or visiting Lego land or Angry birds parks.
I spend in Johor Bahru just one day and it was my last stop in Malaysia. The city doesn't seem nice as it's big, smoggy and dirty.
Johor Bahru is the state capital of Johor. The visitors commonly head for Johor Bahru's royal palaces and lively night markets, considered as some of the state's best attractions.
Have an open mind. JB is so large. Explore into inner JB known as Iskandar where huge malls & hyper marts sells almost anything u want so cheaply. Eateries& restaurents lined every road & streets. Very nice & tasty. Importantly, they still serve customers unlike Sg! Portions are bigger & value for money. Be 2prepared to spend a whole day indeed!
