Every Sunday, Columbia Road transforms into London's best flower market. Wholesale prices — £3-5 for bouquets costing £20 in shops. But it's Sundays 8am-3pm only, best flowers go early.

Surrounding shops open specially for market day — Vintage clothes, independent cafés, antique dealers. Much more authentic than Portobello Road. Get there by 9:30am to avoid worst crowds. Bethnal Green tube closest. Bring cash — Most vendors don't take cards.
