Unico Gelato & Caffè

Part gelateria, part patisserie and part bakery, this St John's Wood spot covers an impressive amount of sweet ground, from gelato and cakes to baked treats. Its hours are remarkably generous — 7:30am until 10 or 11pm, seven days a week — so it suits a morning coffee as much as a late-evening dessert, with dine-in, takeaway and delivery all available. A 4.3-star rating from more than 550 reviews suggests it does the lot rather well.
