Best Places To Eat: What To Do in Marathon, FL

No Name Pub on Big Pine Key

Not too far from Marathon is one of the Keys best-known dives – No Name Pub. No Name Pub is a kitschy Florida landmark, and if you’ve never been, you have to go – if for no other reason than to say you’ve been there.

The pub has a “colorful” history, including being the site of a brothel, and then a General Store, and now, as a pub.

They serve what I would classify a little elevated pub food, and it’s pretty good, with some darn good drinks! But the true character of No Name Pub comes from the “eclectic and unsual” decor….to be in the know you have to visit No Name Pub!

Castaway Waterfront Restaurant & Sushi Bar

I’m going to tell you this is one of our favorite restaurants in Marathon! Jim and I were in the Keys for a month, and we ate at Castaway a LOT! Their hogfish is to die for, and their sushi is fantastic! The fish you eat was probably swimming in the ocean 12 hours ago! Don’t miss a stop at Castaway!!
