Hidden gem of a gallery space, hidden away in leafy NW8 (just off Abbey Road). I've lived in NW London for almost 5 years and only just discovered it. The current exhibition on Sir William Rothenstein and his close contemporaries is well worth seeing - particularly good to see the stunning Day of Atonement by Jacob Kramer.
Nice to go into an Art Gallery on a Saturday afternoon and have the entire place to yourself. A calm, well-curated space.
