I've been to Lerici twice and have eaten there twice, and both of those meals are among some of the best I've had in my life. World's Worst Blogger that I am, I don't have any pictures of that food, so you'll have to go see it yourself.
The first time I went to Lerici, I had only been dating Daniele for a few months. We went to Lerici for what was the nicest dinner we'd ever had together at Bontà Nascoste--the kind where they put everything together next to your table and tell you about your foods as they serve. It was our first time traveling together, I was just coming off of the flu, and I fell asleep in the middle of the meal. Even through my grogginess, I still remember the food being amazing. And we later found out that the Italian medication I was taking caused drowsiness.
Luckily I was a lot more conscious for my next visit, where we stopped by Il Frantoio for some seafood and pasta. That was amazing, too.
Sorry this guide thing is all about food, but it's really important that you know how good the food is here. Aside from that, Lerici is yet another really beautiful town, with a nice beach and castle and colored buildings and alleys to walk through. It is also much more of a vacation spot for Italians than for foreigners, which makes it a nice escape from tourists. It's just a ferry-ride away from the Cinque Terre or Portofino. Parking was also totally doable (or at least it was in the winter).
Also, the poet Percy Bysshe Shelley drowned here in 1822.
