Sure, I can suggest some places. Locals often favor restaurants that provide comfort food, such as VFW breakfasts and Richardsville's chicken dinner. To find genuine, family-owned eateries among the Applebee's and chain delis, search no further than the local historical society.
The Green Wolf Brewing Company, located in the historic Downtown building, is one of the top-rated locations in town. The drinks, lunch, and dinner menus all have a strong sense of local flavor, which helps support a sense of community.
In the afternoon, locals congregate at The Copper Penny, a charming café that offers a menu of American comfort food.
Places that offer food delivery also offer food reviews from online food blogger websites and apps such as YELP, Zomato, Trip advisor, Google, etc. which are excellent places to learn about eating places where people can order takeout or eat in. You can also check websites like KwickMENU, which lists restaurants in the area that provide pickup, delivery, and dine-in options.
For tourists, it is best to first check review websites to determine which locations are worth visiting. Do not be misled by establishments that are listed in the city'80s or 90's on review sites; they are probably paying for advertising to be listed there. Ignore the star ratings and focus on the feedback left by consumers. Reading the complaints will often reveal what can be expected. Check to see if the menu needs to be improved, but take suggestions from reviewers with a grain of salt. Look for entries that accurately reflect your sense of taste.
Locals often have different preferences than visitors; they are looking for comfort food that speaks to their soul rather than their stomach. Ask a neighbor for advice. They may be able to recommend some amazing taco trucks that are not listed online or are only known by word of mouth. These kinds of places will always be busy, but always delicious.
