Wasted Grain is one of my favorite modern bars in Scottsdale. They're happy hours are based on this stock system which I thought was pretty cool. They base the prices of drinks on how many get bought in a certain time period. For example if a lot of people buy blue moons they will increase in price and vice versa. Overall the atmosphere in the bar is great. They have live bands on weeknights and weekdays. On weekends they open upstairs and play more party-type music, while downstairs is more chill and relaxed, so there is a place for everyone in the bar whether you want to just enjoy a drink or "turn-up." Overall the few times I've been there have been really fun and I've meet a bunch of very cool people there. Would recommend 100%!
