Chinese restaurants, even in Taiwan, are notorious for not cleaning their dishes very well. I suspect that’s why hepatitis was historically endemic in Taiwan. One solution that is in common use here is to outsource the washing of dishes.
Restaurants can contract with a company to supply clean utensils. Trays of utensils are delivered to the restaurant, on demand. The utensils come sealed in shrink wrap. Each package contains a plate, spoon, soup bowl, tea cup and drinking glass.
I’ve eaten in a dozen different restaurants, and used the same company’s utensils.
No hepatitis yet, knock on wood!
