Do they sell sweet soy sauce..everywhere I go they only sell regular soy sauce not sweet and everyone I talk to hasn't heard of it but I know it exists.

Look for ABC sweet soy sauce. I thought it was available. Otherwise, another place I recommend is Kam Man Market in Quincy. Google for the address, but it is something like 209 Quincy Avenue, Quincy, MA. This latter place will amaze you. It is BIG, and has almost every Chinese food stuff you can imagine. They also sell kitchen utensils. Across the street, there is another big store, Lucky Grocery, also quite big. This area is worth a visit.

I go to Kam Man. It is amazing. I have friends that shop there weekly from Westwood.

Yes they do it is called dark soy sauce and i have a bottle of it in my cabinet that i got there they have everything
