A hotel's bar is usually a bar-and-grill type place, serving part or all of the menu that's available in the attached restaurant. When I'm traveling alone I usually sit at such a bar to order dinner. Partly this is because I hate sitting at a table all by myself. The bar format makes it easy to strike up casual conversation with other patrons. And when ordering a meal at the bar there's no reason to feel like you don't belong there simply because you're not paying for alcohol.
