Two squares in one: a colourful but now souvenir-heavy market by morning, then a raucous student-and-tourist drinking scene at night, with the brooding Giordano Bruno statue marking where he was burned in 1600. The honest fit split: come for the after-dark crowd and cheap drinks, or skip it — if you want a real Roman market, the Testaccio market or Mercato Trionfale near the Vatican deliver groceries, not fridge magnets.
