We're returning for a week to Positano and would love to try some restaurants we don't know along the Amalfi Coast (we have a car). We've been to Villa Maria in Ravello, but never tried Cumpa Cosimo - is it worth giving up the view? We're also considering Don Alfonso in Sant' Agata and Il Ritrovo in Montepertuso. Are they both worth a trip? Last year, we ate at a restaurant with a view across the street from Dona Rosa, but we've never been to Dona Rosa. Should we go? We love Max and Buca di Baca in Positano, and Da Gemma in Amalfi, but we're open to other suggestions in and around Positano. Also, since we're prone to drifting, I haven't made any reservations ahead of time. Will these places be hard to get into the last week of June if we don't reserve right now? Thanks for all help.
