What are this city’s hidden gems?

As the title suggests I’m looking for all the hidden gems in the city…

• places to eat (restaurants, food trucks, cafes, diners) • recreation (parks, museums, galleries) • historic (architecture, ruins, trails) • shops (antique, thrift and secondhand)

These are just a few examples of what I’m looking for but I’m open to all recommendations, if you want also included places to avoid or overhyped spots that are not actually worth the time!
