You can order fish and chips, seafood meals, and other menu items through the John Dorys app and earn rewards points with each purchase. These points can be redeemed for future meals. The app also allows you to find the nearest John Dorys restaurant. However, based on reviews in the app store, users have experienced issues with the app crashing, being charged multiple times, and long delivery times. Some users also report that the app prices are higher than ordering in person.
