First off, I feel like a social pariah for my indifference toward Stone and Vine; my entire family loves it, and yet I cannot seem to warm up to the place. Although the service is consistently adequate (especially when I go there with my dad - he likes to flirt with all the cute waitresses), the food is for the most part unremarkable.
On a lighter note, Stone and Vine is a great addition to the neighborhood. Central Scottsdale is sorely lacking in the wine bar department, so it's nice to see such a place establish itself in the area. The happy hour is pretty great as well - I am a fan of the Margherita pizza (which I believe is $6 between 5 and 7) and the Zuppa de clams. Their wine selection is limited in comparison to other wine bars, but I still have no real complaints here.
I also think it is a tad overpriced for what they serve, but they tend to appear on Groupon quite frequently ($20 for $30 worth of food - or possibly $15 for $30) which makes dining there worthwhile. It is also quite family-friendly, which is perfect for the typical clientele in the area. Overall, I would recommend giving Stone and Vine a try... the restaurant has great energy and the service is good - it also has a very local feel, which is somewhat uncommon in the central-north Scottsdale restaurant scene.
Bon apetit!
