We made reservations for a wine tasting at this place in September. I havent been there yet but heard good things about it on TA. Maybe someone has some comments on it.

Hello Lollylula,

After you go to a nearby vineyard, do have some Vernaccia di San Gimignano white wine in a nice restaurant in the wonderful hilltop village in San Gimignano itself at either "La Mangiatoria" restaurant located at Via Mainardi 5, or else at "Ristorante il Pino" at Via Cellolese 8. You won't be disappointed.

Dear Lollylula:

Longtime concierges of one of Florence's most reputable 5 star hotels as well as President of the "Tuscan Gold Keys Association" created an out-of-this-world tour company. They know every crevice of Toscana and most if not all vineyards. They tour in-depth and with much animation, all the vineyards from San Gimignano, Chianti to Montalcino. Visit their site at: tuscansunshinetours.it

You will have a fabulous experience at a nominal rate!

Have a great vacation!
