My suggestion is not to take bus or anything..just walk
Once i toured around Geylang, not onli those brothels, but
surrounding shops from Lorong 20 onwards..there are many old shops
selling odds and stuff, plus some old shophouses converted into
mini Buddhist temples..got very mystical look around them...
How about those aquariums or antique shops along the road? Once I
saw this $388,888 red arowana on display, i kid u not.
Lim Chu Kang is also a good place to explore, especially along
Jalan Batera and CCK Road...
