Omega3

Omega3 runs a compact fish-and-wine bar directly on Platis Gialos sand, using high communal tables and stools rather than linen and armchairs. Seafood eaters share amberjack tiradito, shrimp ceviche, scallops, sea urchin and crayfish orzo while beach traffic passes within arm's reach.

Our take

Ceviche on a beach stool

Omega3 runs a compact fish-and-wine bar directly on Platis Gialos sand, using high communal tables and stools rather than linen and armchairs. Seafood eaters share amberjack tiradito, shrimp ceviche, scallops, sea urchin and crayfish orzo while beach traffic passes within arm's reach.

Small plates average high for their size, and premium reservations may require card details or a deposit. Book the sea-facing bench, order four dishes first rather than the suggested six and avoid exposed seats during a strong southerly wind; service can turn inattentive when every stool fills.

What visitors say

Alpha Guide scores Omega3 14.4/20 and current diners praise raw seafood and wine advice; recurring 2026 criticism concerns small portions, high prices, deposit terms and uneven service.
