Based on a sampling, you extrapolate to all Asian food.
The type of reasoning in this statement is inductive reasoning. Inductive reasoning is a method of reasoning in which general conclusions are reached based on specific observations or experiences. In this case, the individual has eaten at various Asian restaurants and has observed that the food tends to be salty. They then generalize this observation to conclude that Asian food, as a whole, is salty. It is important to note that inductive reasoning does not guarantee certainty, as conclusions are based on probability rather than absolute truth.
