Which are the best wineries in the Niagara region to tour? I'm trying to plan ahead for the summer months...I haven't been in a while and I'd love to head down with a few people for tours and tastings. I'm interested in the "atmosphere", the tours, the flexibility (do you have to book in advance?), the quality of tastings (location, cost, amount, availability, etc.) and general experience...as well as the quality of the wine, of course:).
Oh - and also, are any of the associated restaurants worth recommending?
Thanks so much in advance!
