In Vietnam, the cost of oysters ranges from 35,000 - 50,000 VND/kg for whole, unprocessed oysters and 60,000 - 90,000 VND/kg for shelled oysters, with fully processed oysters being more expensive. In contrast, the Netherlands offers free oyster digging during the season, which lasts from September to April, with a daily limit of 10 kg and a free instructional app to learn the skills. The city of Goes is famous for its free oyster digging locations and allows the consumption of oysters on the beach. Oysters are typically cooked in the shell in the Netherlands, and absinthe is often paired with oysters for a unique culinary experience.
