About Brussels
Brussels is underrated — everyone goes to Paris or Amsterdam and skips Belgium's capital. Grand Place is one of Europe's most beautiful squares, the beer scene is world-class (700+ Belgian beers), and the chocolate shops aren't tourist traps, they're legit. Plus it's tiny, so you can see everything in a long weekend.
- •Grand Place at night when it's lit up
- •Belgian beer cafés like Delirium Café (2,000+ beers)
- •Manneken Pis (overhyped but you'll see it anyway)
- •Atomium for mid-century modern architecture
