Casa do Frango

You'll know Casa do Frango by the smell hitting Southwark Street first—that intoxicating char of birds rotating over open flame. It's proper no-nonsense Portuguese cooking: they've nailed the formula of perfectly seasoned piri-piri chicken, crispy skin, tender meat, and they're not messing about with gimmicks. The place itself is casual and buzzy without trying too hard, with that neighbourhood restaurant energy where everyone seems to know what they're ordering. At these prices (mains well under £15), the 4.7-star rating makes complete sense. People come back constantly because it simply works.
