I did manage to locate it in a place called marty's liquors, on the corner of Commonwealth Avenue and Harvard Avenue in Allston. Take the Green Line T out past packards corner. Two more stops. Get off at Harvard Avenue. There's a Pizzeria Uno there. Across the street you'll see Marty's. They have a hell of a selection of hot sauces from all over, by the way.
Drink Pampero with coca cola or even with pineapple juice. It's delicious.
LOL, Marty's been there. I lived in Brighton/Allston for a bit and there are Quite a few fit BU/BC girls in that area. I lived in a Brazilian area- couldn't fathom that- bastards could not make a pizza.
