This is the largest L.L.Bean that I have ever visited. I didn't notice that there was a 2nd story until about an hour into browsing the store. And the nice thing about it is that they sell some stuff that's not available online, like a bean boot keychain. They also have superfeet insoles for you to try on so you can find the right fit. The people working in the store are really knowledgeable about the fit of their shoes, product maintenance, etc. and are really happy to help.
In front of the store, there's a giant bean boot statue, and a giant LLbean backpack that you can pose and take photos with.
This was the most fun I have ever had in a camping goods store.
