I went to Johor Bahru with a friend one day with nary more than 50 singapore dollars to our person. We exchanged this to the local currency and got 100 malaysian ringgit for it. Out of this dosh my friend and I were able to do a lot more than we could have ever done in singapore with the amount. To give you an idea, we were able to .. eat at Sundanese Restaurant and fill ourselves oh so heartily, watch a movie, window shop (yea this one's free), and eat Pizza Hut. Now, if you've been in Singapore long enough - you know 50SGD is not enough fund for all these.
