There are several good asian bakeries in Chinatown. My favorite so far is Eldo Cake House on 36 Harrison Ave. They have an assortment of pastries that you can buy by the slice and fruit shakes too. My wife bought me a birthday cake from there 2 weeks ago and it was delicious. If you haven't tried a Chinese cake you should try it because it's not so sweet and just tastes better all around.
Any other bakeries I should be aware of? I'm always looking.
