Honest 2026 review of Bleeding Heart Bistro in Farringdon — Robert and Robyn Wilson’s 1983 French institution in a cobbled yard off Greville Street. Andrew Barber’s beef cheek bourguignon, sommelier Frédéric, the £20 four-glass tasting flight, and one of central London’s best-value set lunches at £28.95 for three courses. London Reviews verdict: 4.6/5.
