I just came back from Puerto Rico and had really awesome ceviche. From what I understand it is Peruvian; are there any Peruvian restaurants in boston that do it well? I've done some HW and read about Rincon Limeno in E Boston as well as Zocalo in Brighton. I'm craving for the best ceviche in boston! Even better if they have octopus ceviche in addition to the traditional fish ones. Thanks!
