The hike from Positano's ferry was a bother and a half: 4.5 miles, 2,500 ft change in elevation, and blaring sunshine. But the restaurant at La Ginestra was worth it.
Pushing through the dusty and exposed final few hundred yards uphill is rewarded with a stop at Chiesa Santa Maria del Castello, an earthy pungence from unseen cattle, and, more importantly, a water spigot. Mind the bees, though. An iron spiral stairwell provides access to the church roof. I'm not sure if you should climb it, but I do know no one will stop you.
The air here feels about 20 degrees cooler than the base of the mountain. Cool off a bit, and walk the last stretch of blessedly gentle asphalt to La Ginestra. Unlike in Positano's twisting alleys and stairwells, Google can find you and point the way here.
La Ginestra may appear empty. Is this yet another establishment closed for the tipico August vacation? No. Simply wander a bit, calling "Ciao" and "Hello" until a short sexagenarian woman appears. She only speaks Italian, but has a good ear for Spanglish. Ask for a seat outside (pointing suffices) to enjoy the breeze and the view of Naples bay.
Like any Michelin rated restaurant, there is no menu. You will enjoy what the chef prepares. I had an antipasto of mozzarella, soft white bread, eggplant, fried green beans, prosciutto, and a lovely fried dumpling whose name I never caught. Next course was a sumptuous eggplant pasta in alfredo, sprinkled with basil and Parmesan.
Google translates the style "contadina" as "peasant," yet it is the epitome of pleasant.
