There are a number of mediocre locations in the Lerkendal Stadion to get food and drink. Generally, it is quite expensive and the quality is not what you would hope for.

Your best option is to eat in one of the amazing restaurants the city offers before or after the game instead of eating at the stadium if at all possible.

The Lerkendal Stadion is quite a well known one in the footballing world, and despite being in Norway, often plays host to European nights, and even a European Super Cup final or two. As such, there are good food and drink options. The favorite half time snack amongst Norwegians is a simple sausage in bread, though it certainly goes down a treat, you can also buy a variety of drinks in the concourses.
