A museum the way we like 'em: impressive and small. Enjoy a fancy Louis Kahn building, and look at early Italian paintings, African sculpture, and modern art.
Opened in 1895, Louis' Lunch is recognized by the Library of Congress as the Birthplace of the "Hamburger Sandwich." Although this is probably not true, New Haven still claims to have invented the hamburger. Don't let history get in the way of you enjoying a great burger.
Yale library of rare books, and a really incredible building. For more info: https://beinecke.library.yale.edu/exhibitions-visiting/hours-and-accessibility
New Haven's best that rivals anywhere else's best. Yes, including New York. Chicago, please. No one's talking to you.
Favorite park in New Haven. 22 acre park with greenhouses a large fountain and community gardens.
My mom's favorite. Get the mash potatoes topping and enjoy life.
