Union is a nice cozy place set on the fringe of Old Town Scottsdale. The inside has a nice homey feel with booths that have extra throw pillows (love that) and soft lighting and desert scape paintings. A big drawback is that while half of the seats face the lovely paintings the other half face the kitchen.
The wine flights are good but the pours are inconsistent and not as hearty as in some places. The bulk of their wine menu comes in bottle form. They do offer 8 oz pours of wine for about $15 a glass. Be careful when you order, as we were given 8oz pours and had no idea we were getting them.
The food was quite good, they actually had real grilled focaccia and this garlic cream butter that was delicious. Its tapas style and we ordered three and it was more than enough for the two of us. All of the tapas we ordered were well prepared. We also ordered dessert which was very mediocre.
I would come back again but probably for a happy hour. As far as food goes it wasn't my favorite at a wine bar. They do have a patio out front that looks like it would be very cozy on a cool evening.
