Stayed at the westminster last year. over-priced and definitely faded edwardian (not so charming). Would not recommend.
Chateaux Montreuil (Relais) with 1 or 2 michelin stars my favourate restaurant in the world, but about 30 minute taxi ride from Le2K.
You could try a B&B which have found very comfortable and convenient, with en-suite rooms at about 50 euro (from memory). Actually just behind the Westminster and owned by the family who also own the Flavio restaurant next to the westminster (which is very good)
