Stopped by e-Tea Cafe on Castro Street tonight to get a drink. It has a dizzying array of crepes (e.g., pastrami crepe), Double Rainbow ice cream, and cakes, plus the usual pearl tea drinks. But I wanted something light and ordered fresh watermelon juice with boba, $4. The boba were just the texture I like, still chewy and not too soft. But the watermelon was underripe and lacking in flavor. Anything else good here?
