Essentially shipping container converted into a coffee stop. There are no seats so everything is grab and go where you're free to explore the hip and cool streets in the area. Chaiwalla serves up the standard coffee but seem to specialise in cold beverages Vietnamese coffee, Thai milk tea, and customized frappes. I guess it's only fitting for the hot and humid weather. A worthwhile stop before heading over to queue for some awesome bread at Hiap Joo which is just round the corner!
