When browsing Yelp and Tripadvisor reviews in Italy, you often see "best meal in Italy" but I…read morepromise you this really was our BEST meal in Italy. La Sosta was recommended to us by a foodie friend who went 5 years ago and urged us to get the gnocchi.
Everything we had was excellent, well-seasoned, and very reasonably priced. We ordered a bottle of wine and was recommended a Chianti from a vineyard 2 km away (18 euros), perfect.
We started with the octopus and antipasti platter, my favorite being the soppresata and fried chickpea 'chips'. Next we had the gnocchi (made from potatos only, no egg or flour) with a light cheese sauce drizzled with honey - the first bite felt like heaven, light fluffy nuggets of delicate deliciousness. Next linguine with clams, wild boar pappardelle, slow roasted beef (for 5 hours), and steak tartare (my favorite, a very light steak tartare, no egg, with red onions, pecorini with truffle, and pistachio!), definitely the best steak tartare I've ever had. Everything was good.
For dessert, Sicilian canoli and a mango pudding/panna cotta type dish paired with coffee. Note: The Americano might be the best cup of coffee I've ever had, they use Jolly Caffe (seemingly generic coffee you can buy at supermarkets, local to Florence).
I can't recommend La Sosta enough. Take a taxi from Florence to Settignano which will cost you 15-20 euros, it's totally worth it plus you get to see a cute Tuscan town. Perhaps go in the day when you can get a view of the countryside on the terrace. BEST meal in Italy!
