I really wanted to like this place! But it was just so bad! Went on a Saturday around 6:30ish, it wasn't too busy and they were really well staffed (I think there were 6 people behind the bar). Despite this it still took a solid 15 mins before anyone even acknowledged us. The bartenders weren't knowledgeable at all though-- I'm def no wine snob but one literally responded to a question with "it's a red wine from France"... You order each tasting 1 at a time and it took at least 10 mins after we were finished to get someone's attention to order the next. Weirdest part was the bartenders were all right there-- cleaning glassware, organizing wine, making food (yes, they make food right at the bar. Simple stuff but it was still a little awkward-- especially when they're snacking on that same food amidst everything else going on)... Maybe their staff is reaaaally new but we interacted with several so it seems more like a management problem.
Moral of the story-- there are much better wine options in Scottsdale, save yourself the headache and go somewhere else
