The po' boys and girls of Miami-Dade don't have access to many real po'boy sandwiches. You can't blame Larry and Elena Robinson for this, because the husband/wife owners of the Rumcake Factory get their authentic version out to as many people who stop by their cozy café/take-out shop in North Miami Beach. The soft French bread that frames the po'boy is the official loaf that gets shipped fresh from New Orleans. Between the halves is your choice of cleanly fried shrimp ($8.50) or catfish ($7.75), with lettuce, tomatoes, pickle slices, and homemade rémoulade dressing. Sweet potato chips come along for the ride. Other po'boys here pooh-pooh the notion that fried fish has to be the filler: Fried turkey and pulled pork po'boys redefine the genre. Dessert is the namesake rum cake — a best in its own right.
