Plaza Mayor in Madrid.
Big street festival in center city now. Food, booze, music, various vendors. The usual kind of thing. All good, but we should build more spaces that allow people to eat and drink outside on a regular basis without having to close off several city blocks, and relax restrictions on commercial activity and adult beverage consumption in some parks. It's something people like to do, and there actually are few places they can do it regularly in this country.
