This area is where you will find Singapore's red light district. Although it isn't quite as easy to locate as I was led to believe. The suspicious looking vendors with a variety of sex related drugs along the pavement is a indication that you are in the right area, but the assortment of brothels, girlie bars and alleys filled with prostitutes is found a little deeper than I was comfortable to venture. 
 
I spent some time browsing the variety of food vendors/restaurants in this area, which clearly lures in the crowds as each one was busy with locals enjoying steaming bowls of noodles, plates of seafood and buckets of tiger beers. There were also countless options where you can sample a variety of innards, which are perhaps less than appealing to most westerners stomachs. Don't let that or the lower standards of cleanliness put you off, some of these are the best places to eat on the island. I was a little startled to see a cockroach run across the pavement and the grime along the street is a complete contrast to the majority of Singapore, but this is truly like 'the real' SE Asia that I have come to love. Come prepared and with an empty stomach and you won't be disappointed.
 
Interestingly, during the daytime the area has a much more spiritual atmosphere with huge temples and mosques and pretty shrines.
