The food and drink at the ground really isn't anything special with there just being a few piecemeal options available that you will find at any football ground in the country such as Hot Dogs and Burgers. My advice would be to either bring some food in yourself – or better yet, hold off eating until after the match and then pick a restaurant and enjoy some awesome local fare, restaurants often are open later in France than most other countries so it won't be hard to find something delicious.

Once the Stade Saint Symphorien opens its doors, you will not stay hungry. There are 14 shops with different snack choices, where you can eat something light and have a coffee or soda. If it is fast food you crave, you can visit one of the 3 stands with French fries or have a kebab—there are two stands inviting you to enjoy.
