Crack open your favorite crustacean with a deal in honor of National Lobster Day coming up on September 25th. ArtBar is offering a steal that you’ll want to snag — a 1 1/4 pound lobster along with a creamy cup of clam chowder for $29. Stop by the Cambridge spot, which sits right along the Charles River and has epic views of the city skyline, between 5:00 and 10:00pm from Sunday, September 22nd to Saturday, September 28th. You might want to stick around for your chance to grab one of their famous fire pits before the season’s up. Make a reservation for dinner here.
