Santo Remedio Taqueria, Shoreditch

You'll find yourself on Great Eastern Street surrounded by the usual Shoreditch mix of galleries and vintage shops, but step inside Santo Remedio and you're transported. The place has that unpretentious vibe where they're not trying too hard but clearly care about getting things right—the kind of spot where locals queue at lunch and it stays packed into the evening. The tacos are the real deal: slow-cooked carnitas, charred fish, proper salsas made fresh. Pair them with their mezcal list and you've got the kind of meal that makes you wonder why you ever bothered with the mediocre Mexican chains elsewhere in London.
