I know we're not supposed to spread unconfirmed rumors on this forum, but I think I found Porto's Bakery tarts (guava, guava & cheese, coconut) in the South Bay.
They look and taste just like Porto's Bakery product. Tropi-Cuba has a small kitchen, and from the front of the house, I didn't see the sort of pastry kitchen needed to make a full range of pastries from scratch. So I think they're buying parbaked tarts from Porto's wholesale factory. I'll ask the Tropi Cuba management to confirm next time I'm there.
This place is more than a bakery / cafe. It's been open about a month and a half, and they have a full lunch & dinner menu of Cuban food. Nice looking room in a strip mall across from Harbor UCLA Medical Center. I haven't tried the food yet, but I was so excited to have Porto's tarts without the traffic-laden hump to Glendale that I had to come blab about it here
