True hipster wine dives seem impossible in London (precluded by economics and/or perpetual lowkey class war), you're better off Eurostar'ing direct to B̵e̵l̵l̵e̵v̵i̵l̵l̵e̵ Montreuil. But if you just want awesome obscure wine and ££ nibbles by candlelight, wallet be damned, you could do worse than this tiny Clapton joint (N.B. almost always rammed... but opens at 2pm on Fridays)
