What is your favorite easy way to meet people in your city?

If a few HeartAtlas members wanted to spend a relaxed hour together, what simple activity would you suggest? A walk in a public place, a museum visit, a board-game café, a local market, or something else? Please keep suggestions non-commercial and share only the city or public venue—not private addresses or contact details. What would make the plan comfortable for a first-time participant? — HeartAtlas Team
