Buffet's are a great way to please everyone in your restaurant. You can choose to have a spread of assorted food items or put together a new theme each week.
Some options for themes could be:
Mexican- tacos, quesadillas, refried beans, taco salad bar
Italian- spaghetti, meatballs, pizza
Seafood- crab legs, fried fish, shrimp
Wings- assortment of sauces, vegetable options
Make sure you have all the necessary tools to set up a buffet at your venue. Serving spoons, chafers, plates, etc. Promote this weekly event early to get the word out.
