If you like Singaporean food, have I got a restaurant for you. Unfortunately, I've mislaid the business card and can't remember the name -- Singaporean Cafe? something obvious -- but it's on Mott St. just below Canal.
I highly recommend the achar (raw vegetables with spicy peanut sauce) and the pancake appetizers. I also liked the banana-leaf-wrapped whole fish (it tastes musty -- it's supposed to). There are many prawn dishes on the menu, and we had one that the waitress/hostess/owner recommended, and it was good.
Their version of Pad Thai was a little greasy and not that tasty -- perhaps their noodles are not as good as their fish.
My favorite item on the menu is a dessert/drink they call black jelly shaved ice. I've had it elsewhere, without the ice, where it was called Chin Chow and I was told it's seaweed-flavored gelatin. Here they serve it with shaved ice and surprisingly tasty strawberry syrup. I hate to sound like a Pepsi ad, but it's surpringly refreshing. Very cooling.
This place is better than one of my favorite San Francisco restaurants, Straits Cafe, which is much fancier and much more expensive.
