Where can I find oysters in Turkey: Antalya, Kemer, Alanya or Istanbul?

A traveler reported finding oysters in Alanya. No restaurant, address or price was provided, so this is a lead for further research rather than a specific venue recommendation.

For Antalya and Kemer, the request specifically concerned live oysters in unopened shells, but no suitable venue was identified in the discussion. There is no confirmed address here for buying or ordering them.
