The unofficial count for Italian restaurants in Frankfurt is round 180 so its a pretty good place to be for the Italian lifestyle
I have tried 5 of the best and they have all been authentic from service to quality of cuisine to wines.
Out of convenience i went to a recently opened trattoria 2 doors from my hotel in Kolner Strasse, called da Vinc cucina & vino. Absolutely superb, possibly the best buffalo mozzarella with tomato and deep red prosciutto and a gnocchi with ricotta cheese .
Volare is bigger but retained the Italian flair, good wine list service indifferent but quality of food, wow. Slightly more expensive on the food.
The stand out for me has been Cron am hafen down on the river on Speicher Strasse. Truly Italian great service, cheeky, and very popular. Incredible wine list, cuisine from all regions of Italy. Dinner for 2 including a bottle of Montepulciano was around 100e.but well worth every euro.
Quattro was a lunch visit , good location in the old part of the city, ģood for people watching, good wine list but more germanic in attitude.
having said that i set a fairly high benchmark.
There was very good Italian exposure at the Klein Markt Halle with Italian importers like Casa Italiana, with Francesco Belvedere importing the most amazing array of Italian goods with a specialty on Sicily.
Cafe Valentino, serving up bolognese, ravioli with ricotta a d spinach, and a fine selection of Italian wines.
I will do a separate story on this market but suffice to say i could have easily spent the whole day here, its a must when visiting Frankfurt. As good as any of the leading markets i have been to anywhere.
There is an International Womens club with a big focus on Italian cuisine http://www.iwc-frankfurt.de/index.php/de/aktivitaeten/52-interest-groups-deutsch/455-italian-cuisine
