Hi DJ, looking at your list of Food Centres, they are very "chinese-centric" - if I many call it that.
Can I throw in some suggestions for Saturday morning, since you also like wet markets? Head to the Geylang Serai Market (Paya Lebar MRT). Not only will you get another wet market feel (but don't miss out on Tekka either); but you will also be spoilt for choice on Malay / Indian Muslim varieties. Try the Nasi Rawon at a stall called "Bumbu" near the escalators.
Also, if you can fit it in, and you get space(!) to sit, head to Satay by the Bay (near Gardens by the bay) on NYE. You can have your cheap beer, satay on low stools and tables (like in the old days) and if you drag it out watch the fireworks from there.... and if you cant sleep after that... cab it to Mustafa
