Every island has one of them it seems
There was the Providenciales Thursday Fish Fry in Turks and Caicos. There was the Friday Oistin Fish Fry in Barbados. There was the Sunday Fish in Samoa.
And now the Friday Street Fest in St. Lucia.
These islands seems to have a decompression day every week where everybody comes out and has food and drinks outside with a lot of island music and dancing.
