I will be staying at an apartment-style hotel in Bayswater for one week in September. My room will include a small kitchen, so I am interested in doing some light cooking and heating up high quality prepared foods. Can anyone suggest his or her favorite, reasonably priced food shops, bakeries and markets in London? If they are in or near Bayswater, even better. I know about Borough Market and plan to be there Friday, but what about the rest of the week? As far as supermarkets, I understand there is a Marks & Spencer's at Whitely's shopping center. Is that the best bet for a standard supermarket?
