OK, have been living in Sing almost a year and have tried lots of food of all kinds.
I would like to make one definitive recommendation, Blanco Court Prawn Noodles at 243 Beach Road in the Arab Quarter. The quality is in the very rich pork-based broth.
While it seems odd, the dishes to get are those that mix prawns with pork ribs. You can choose noodles (I like mixed) and choose whether you get it dry or as a soup.
This to me is the key in maximizing the dish. Order dry and then add in the broth as you like to create your own bespoke dish. For those that like heat, get extra spicy and add in just enough broth to make a flavorful accompaniment to the noodles.
Be sure and reserve a table then tell the table number to the lady taking the order.
Large number 5, mixed noodles, dry and extra spicy.
Blanco Court is easy to get to but would be worth going out of your way to have :-)
