The Brighton Super 88 carries Wei-Chuan brand and Prime Food brand xiao long bao, although the Wei-Chuan ones are often sold out. IMO, the Wei-Chuan xiao long bao are on the sweet side, but are otherwise not too bad. I don't like the Prime Food xiao long bao.
This link has a picture of the Wei-Chuan xiao long bao, packed as "Pork Mini Buns" .
I'm not sure what name the Prime Foods xiao long bao has on its package, but you could look for a package with the same characters as the on the Wei Chuan picture.
