"What is ackee?" the newcomer to Sonia's will ask. And the proprietor will answer, "It's a Jamaican fruit that looks sort of like scrambled eggs." Eeeew! But no. Listen. For $5.49, you can get an ackee patty, made with tomatoes, onion, and cod fish, whose fragrant spice and flaky pastry will hook you forever on the savory little purses of joy. Also available are beef, plantain, curry chicken, or vegetable patties for less than $2; shrimp and lobster patties are priced less than $5. The deceptively simple concept (filling, dough) will transport you instantly to a Jamaican beach. Seriously. Call ahead and order in bulk for your next picnic.
