Had oysters and 2 cocktails.

Cocktails were ok. Suggest any future diners to not go for the oysters. Oysters tasted stale, not fresh. Suspect they were frozen, defrosted and iced before served because it took more than 20min to come to our table even though it's a dish that didn't need much preparation and the place was empty. Not sure if I'm gonna have diarrhoea tonight.. 😨
