I live in Genoa wich is far less thah 50 miles from 5 terre, I can reccomand you :)
I Like very much the south part of Italy, from Campania to Sicily, is cheaper than north, and sea is better.
If you plannig to visit Liguria I suggest you to see even the west-side, from Imperia(near France) to Savona, and visit
Wherever you choice to go, I tink is very difficult don't find very good wines, cheeses and amazing cusine ;)
In Liguria Our tipical dishes are Pesto, Focaccia al formaggio of recco, vegetables salt cakes,Pansoti,Ravioli with "tocco", and much more
Thera are also a few of uncommon wines, In 5 terre you have to try "Sciacchetrà"
For every town and every season you'll find a tipical dish:tu
Tell me where you want to go, maybe I can be more precise
Sorry for my poor english, i'm a little busy:w
