I went to a Vietnamese restaurant for lunch and was excited to find they had "Soybean Milk" on the menu. Thinking it would be purely soymilk, I ordered a glass...it was mint green and thick, like a Shamrock shake (sorry in advance for a McD's reference). I had difficulty communicating w/ my waiter about its contents, but tried a tiny sip and it was really, really sweet...not your standard soymilk. I didn't trust the looks of it so I stopped right there. Anyone familiar with a mint green-hued "soybean milk"? I just want to know if it was indeed soymilk or milk-milk.
