As far as dimsum goes, New Moon offers nothing really special. It is a dimsum joint, similar to Yummy (reviewed earlier) that has a sorta buffet display up front, order what you want, pay first, and you can sit down inside. And they do have a more extensive menu. They are known for their fast service, with stuff often offered in pre-packed to-go boxes so you can grab one quickly for pretty reasonable prices (typically dimsum is about $1.00-2.00 per piece, depending on how specific items, no matter where you go in Chinatown). I needed some food to go, so I went inside and ordered a box that contained 3 daikon cakes 蘿蔔糕 and 3 shumai (they look pretty dark, so they're probably beef shumai) for $6.50. These shumai are regular sized, so price is about normal in Chinatown, maybe a LITTLE discounted, as they are a little colder than normal. They of course have a lot of other stuff available and some Chinese-only items (sorta secret menu). Worth trying? Sure, but as I said, nothing real
