I saw a couple of Brazilians with the "Spice" moniker, but their service was so horrendous I didn't go back. At least one Brazilian was reported to be ok though. If you go, I'd recommend approaching as if they were Romanians... get a sense of their attitude before paying, and walk if there are any red flags.
There was an amazing hot and young Brazilian with great service here about a year ago, and at a great price. But she changed cities and put her price way up. I don't think she was ever affiliated with this group.
There's actually a lot of new faces in Cambs at the minute, including new Romanians, Columbian, and others. But all are questionable.
