The cafeteria at the Kangerlussuaq Airport is probably the largest of the few eateries in town. The cafeteria typically serves standard offerings such as sandwiches, burgers, curries, and other European fare.

The 'upscale' restaurant adjacent to the main airport cafeteria located through the far doors at the end of the cafeteria is quite pricey, but, offers Very delectible native Greenlandic meals with Reindeer, Musk Ox etc along with a nice glass of wine which is hard to come by.
