Are restaurants retailers?

Hotels and restaurants are considered part of the hospitality industry.

I think that restaurants could generally be considered retailers. If you look at retailer associations, some say they include restaurants or have a restaurant division. Others mention them separately (e.g. the Alaska Restaurant and Retailer Association). A retailer is defined as the seller of goods or commodities in small quantities directly to consumers, so it sounds like technically a restaurant fits the definition. That being said, I think the average reader thinks of a store or online business (that sells groceries, clothing, books, etc.) and not a restaurant when they read "retailer."

I'm not sure how I'd group the words you mention. Is this for a travel/tourism article? Who is the audience? If it is for visitors to an area, maybe local attractions would work.

My impression is that a retailer sells goods that others have improved upon or made. According to a few dictionaries it seems related to tailler (Anglo-Norman) meaning to cut. It seems that tailor is a related word. I agree with JLG-- I think has the idea of "re-cutting" material for sale. I think a better choice might be something emphasizing hospitality. How about the "hospitality community?"
