Abuelo

You'll find yourself on a quiet stretch of Cavendish Place, just north of Oxford Street, where Abuelo sits like a proper little slice of Spain. The kind of place where locals pile in for breakfast, where the coffee arrives in proper cups and the staff actually seem pleased to see you. There's something refreshingly unpretentious about it—think marble-topped tables, vintage tiles, and the smell of good espresso mingling with jamón. The Spanish breakfast spreads are genuinely excellent, the kind of thing that makes you wonder why more London cafes don't take their food this seriously.
