If you get hungry late at night (or very early in the am!), then you might want to check out GopherNow; it’s a directory of restaurants, diners, and cafes that are open all-night or otherwise during the wee hours. There are only three entries for Great Falls in the “24-hr” category: Good Time Charlie’s, Tracy’s, and Burger King, but there are other entries for “regular” (non-24 hr) restaurants, too. Address, phone number, and even some menus are also listed…pretty handy. You can register and enter restaurants over there if you’d like.
