wanton mee from Hong Kong, but very good in its own right and probably one of the best in Singapore. It's sweeter than its Hong Kong counterpart with a different set of ingredients, such as char siew, veggies, chicken, mushrooms, greasy fried wantons, and a good chili sauce to taste, together with the obligatory noodles and soup. I got the S$6 (US$4) version, which meant "extra noodles," but I was still hungry for more. It's open late, so come by for a post drinking snack.
And always remember to ask taxi drivers where they eat themselves, as you know it will be good, cheap, and open late, as long as they are not getting a kickback from wherever they take you.
