You might be surprised to know that there are some Maine restaurants over 90 years old, and some even older than 100 years old.

Can you believe these spots were serving up delicious food before World War I, or even before the Titanic sank? (Rose should have let Jack get on the door...)

Well, if you're up for a tasty road trip, it's time to hop in your car and prepare to eat at some legendary restaurants that continue to stand the test of time.

What Are the Oldest Restaurants in Maine?

One of the oldest restaurants is Boone's Fish House & Oyster Room, dating all the way back to 1898.

While you can, of course, get seafood and even some steak, the Portland restaurant has a signature dish. According to its website, that would be the baked stuffed lobster.

Interested?

Apparently, it was invented back when the place first opened, way back when, and the restaurant says it still serves it the same way: "stuffed with fresh Maine seafood and a perfect blend of savory seasonings."

And that's just one restaurant still thriving today. Let's take a look at 7 of these spots still going strong in the Pine Tree State.
