I will be travelling in Europe this summer with family and I'm looking for restaurant recommendations! Would like a restaurant for lunch and dinner! This is what we have so far and what we need:
Florence (3 nights): Borgo San Jacopo, Enoteca Pinchiorri (need places for Sunday lunch and dinner)
Helsinki (4 nights): Olo, Demo, Ask, Savoy, Nokka (need places for Sunday lunch and dinner)
Sweden (4 nights): Oaxen Krog, Operakallaren, Esperanto, Mathieu Dahlgren Matsalen, Matbaren (need places open for lunch)
Oslo (3 nights): Kontrast, Statholdergaarden (need places open for lunch and Sunday dinner - thinking of Arakataka)
St Petersburg (2 nights): Il Lago del Cigni (with a family friend here so I think we are good... However, would like to know if Il Lago is a good place to take close friends)
Moscow (4 nights): La Colline (need everything)

We're doing good in Copenhagen / Berlin
If you could tell us whether the chosen restaurants are nice that would be appreciated!
Thanks guys in advance!!
Could not get a table at Frantzen, and obviously at Maaemo

I can only speak for Florence. You should consider a meal at Villa San Michele - see http://www.belmond.com/villa-san-mic...ts-in-florence

Ask for a table on the outer side of the Loggia (see photo). Also arrive early so that you have time to admire the main building and the gardens.

That looks really nice!! Thank you!

I couldn't find the menus however do you know where I can find it?

Scroll down the link I gave and on the left hand side just above La Loggia Bar you can download the menus (a bit out of date though). The dinner menu is here - http://4c6c364fdf1082a37bcf-54493dc0...gia_dinner.pdf

Thanks!

Also on Borgo San Iacopo, Osteria del Cinghiale Bianco is open on Sunday for lunch and dinner. I got the recommendation here on fodors and went there last month. I'm glad I did, it was delicious.

I also second the Osteria del Cinghiale Bianco but if you are having a full dinner you may want something lighter for lunch.

If in Florence on Sunday I would highly recommend La Catinetta dei Verrazzano - http://www.verrazzano.com/en/la-cantinetta-in-florence/

The wines are excellent and the mixed plates of salume, cheeses etc are excellent.

Thanks guys!
