Has no-one suggested the Four Floors yet?
Funnily enough I had a beer in the Mustang bar last Tuesday (was with a Sing newbie, right of passage etc).
I have nothing to add to the above as they are all good suggestions but I’m partial to a walk around Pulau Udin island, especially when you catch the ‘bum boat’ from Changi Point.
Not a fan of Maxwell food center (my Singapore office used to be down the road in China Town) but there is a good one if you continue walking up South Bridge Road with the Maxwell Food court on the right, through china Town and up to the Upper Cross Street junction, across from that is the Hong Lim Food Centre, less touristy and one the locals use a lot, has a famous noodle place there but cant place the name.
Went to Penang about 4 years ago for a holiday, cant remember a thing so I guess its not on my ‘to return’ list.
