When you are not sure what to order in a restaurant, do you say to your server, "What do you suggest?" or "What do you recommend?" I have read somewhere that you should ask what the server recommends, and not what the server suggests. I don't understand the difference between "suggest" and "recommend" and why "suggest" is wrong. Please clarify this probelem.
A pedantic waiter would feel free to suggest that you order that which is in the best interest of the restaurant; whatever is most expensive or there is a glut of for example.
If asked to recommend something we are asking for preferences: what they actually enjoy eating themselves.
Being something of a cynic I never bother to ask such questions, partly because I don't trust the "suggestions" I receive but mostly because my own tastes may well be very different from that of the waiter, and finally because it feels to be an unfair question: which of your children do you most like?
