Visited Boston last weekend, and got a great tip from these boards that I wanted to resurrect: the juice stand at the Chinatown Eatery, 46 Beach Street, 2d floor. All sorts of great fresh juices and shakes--papaya, watermelon, coconut, ice milk with red beans, sweet tea. I got mango with pearls--didn't know what they were, but all the Asian young folk in front of me were getting them so I followed suit--sticky, sweet balls of goo. Straws wide enough to suck up one pearl at a time. Perfect accompaniment to Vietnamese food.
