There are restaurants with a wide variety of choices of food to offer.
Movie theaters are pretty much the same thing. Commonly, the concessions/refreshments served are popcorn, candies of various flavors and brands, and soft drinks provided by whoever the company is contracted with. A number of theaters would also be serving hot dogs, ice cream, pizza, burgers(which count as sandwiches), nachos, and/or other snacks/meals.
The Regal theaters in Visalia serve popcorn, candies, ice cream, soft drinks, and nachos. ICEE beverages are also available. They also serve a mix of popcorn with Cheetos in a bag. When I traveled to Fresno during September(I think) 2016 to see the Forestiere Gardens for the first time and to see the new version of "The Magnificent Seven", it was at the Edwards Cinemas, the owner being Regal. The refreshments were popcorn, soft drinks, candy, hot dogs, ice cream, nachos, and coffee courtesy of Starbucks.
Cinemark's refreshments are popcorn, soft drinks in a similar manner to McDonald's, iced tea, lemonade, Starbucks lattes and mochas, ICEE beverages, pizza, hot dogs, chicken wings and tenders, nachos, Cheetos coated in cheese and jalapenos, burgers, wings, quesadillas, appetizers like fries, and desserts. They also serve alcoholic beverages of every variety at a bar. Their website can explain everything.
Maya Cinemas serves tacos among classic choices of pizza, popcorn, confectionery, nachos, pretzels, hot dogs, and soft drinks. AMC's menu is popcorn, candy, soft drinks, hot dogs, ICEEs, churros, pretzels, pizzas, pretzel bites, mac n cheese, mac n cheese bites, mozzarella sticks, chicken tenders with the customer's choice of dipping sauce, salads, french fries, burgers, sandwiches, and milkshakes. Showplace Icon is limited to popcorn, candy, soft drinks, and a bar for alcoholic beverages, appetizers, entrees, and desserts. The menu varies by location, so visit their website for extra information.
One of NJ.com's articles includes a photo of Kerasotes's menu prior to the demise of the theater chain, proving their refreshments were popcorn, confectionery, soft drinks, nachos, pizza, coffee, and Icees. Georgia Theater Company has something called the Outtakes Kitchen + Bar.
A Marcus Theater in Wisconsin sells popcorn, ICEEs, candies, soft drinks, pretzels, and mini doughnuts. Others are selling hot dogs, ice cream(like dippin' dots), sliders by White Castle, and/or pizza. The menu seems to vary depending on the multiplex, especially with some serving fruit snacks by Welch's. Other items are burgers, chicken tenders, fries, and shakes by Reel Sizzle, cocktails, and fancy appetizers by Take Five Lounge, pizza, and other tasty dishes by Zaffiro, plus appetizers, salads, sandwiches, and desserts by Zaffiro's Express. As I said, the website among other sources could explain it better. I'm not going down any rabbit holes.
The Australian chain Village Cinemas offers popcorn, soft drinks, confectionery, churros with ice cream, and other entrees courtesy of whatever The Bucket Boss is supposed to be, burgers, and fries, among other treats. (Their website's security is too damn strict at the moment.) Vue Cinemas currently sells popcorn, candy, soft drinks, milkshakes, coffee, Doritos and other chips, hot dogs, ice bream by Ben and Jerry, slushies, and pick and mix.
My mom's current hands-down favorite, Galaxy Theaters, serves popcorn, candy, hot dogs, pretzels, alcohol (not just at a bar), Icees, ice cream by Haagen-Dazs, Dibs crunchy bites, Toll House ice cream cookie sandwiches, mini pizzas, and nachos. I think I recall them serving sliders and fries from White Castle at one point.
I once looked at the concessions page of the site for Regal back in 2020, and I recall them serving, alongside their usuals, Cinnabon gooey bites, Doughlish cookie dough, Freschetta mini pizzas, Tyson boneless chicken wings, and Nathan's Famous corn dog nuggets. The current site includes PDFs of their current menus, showing the standard concessions being popcorn, candies, Welch's fruit snacks, Nathan's famous hot dogs, ice cream, soft drinks, Icees, and nachos(either Doritos or Tostitos). The expanded menu includes a mix of popcorn with Cheetos sauce or seasoning and actual Cheetos, pretzels, pretzel bites, mozzarella sticks, bacon cheese fries, pretzel sticks with cheese sauce, cheeseburgers, chicken tenders, spicy chicken sandwiches, and pizzas of various flavors and toppings. Visit the site itself for the other PDFs. I don't want to include too many details or worsen the existing redundancy.
