This truck has 4 locations. Off Roosevelt, they are usually at Warren St and 80th Street. I have no idea where the other 2 locations are. The base restaurant is at 94-54 Corona Ave.
Encebollado de pescado – tuna soup
Corvina Frita – fried fish (croaker), comes in a platter with rice
Quaker – I think this is an oatmeal drink
Ceviche de camaron – Shrimp ceviche
Ceviche de concha – Conch ceviche
Bollos de pescado – ball of fish, onions, steamed with corn meal in a husk (it is awesome)
Seco de chivo – Goat stew
Guatita – Beef tripe stew
Carne asada – Grilled beef
Caldo de salchicha – Sausage soup
Agua – water
Morocho – Hot, creamy, corn based drink
These items are on the big sign on the non-window side of the truck. May not be available.
Seco de Gallina – Chicken stew
Sango de camaron y pescado – Shrimp and seafood stew ( I think )
Arroz Marinero – Rice with seafood
