“ Mary,
I have used Premier Inns quite a lot and I can say that i often ask the receptionist where the good restaurants are in town for dinner. They have always been more than happy to give me recommendations and this despite the fact that a lot of these Premier Inns were 'attached' to their own restaurant / pub (Beefeater branded pubs and the like that Whitbread own).
I hear that the High Barnet hotel will have an inhouse restaurant where no doubt some of the residents will eat but a lot will venture the short walkable distance into town.
I am neutral on whether this hotel is a good idea but i do believe there will be some benefit to local restaurants / night time economy. ”
