I have called this a restaurant, although I guess it’s probably better described as a canteen.
The restaurant is part of a series of shops at this place, selling a range of gifts, clothes and foodstuffs. Well worth a look, although it is only the restaurant that is music free (although I did get a bit of nuisance from the kitchen).
The restaurant serves a variety of hot and cold meals, drinks and snacks.
Note that the visitor centre is only open during the day.
Easy to find – you’ll see the Baxters complex from the A96.
