You will find a few restaurants in the larger cities of Liechtenstein. There is also a McDonald's restaurant opened in 1996; serves beer, which is very popular and is widely publicised by road signs throughout the country.
The many small bakeries are a great place to get a warm, fresh roll or pastry.
One recommended restaurant is the Old Castle Inn, Aeulestrasse 22, +423 232 1065, in the centre of Vaduz. It is impossible to miss and offers authentic food at a reasonable price and with a pleasant atmosphere.
