Casa do Frango Mayfair

You're on Heddon Street, wedged between the designer shops and cocktail bars, and you walk into something genuinely different: a Portuguese rotisserie that feels like it's been here longer than it probably has. The whole room smells like charcoal and peri peri, there's a queue of people who know what they're doing, and nobody's here for the Instagram moment—they're here because the chicken is insanely good. You order by the quarter, half, or whole bird, pick your sides (crispy chips, rice, salad), and it arrives properly golden and still warm from the spit. It's straightforward stuff executed properly, which in Mayfair is basically revolutionary.
