The return of beautiful weather heralds another return to the Valley: event season. Whether you’re going to a wedding, bar mitzvah or charity fundraiser this winter, chances are high you’ll find a mobile bartender slinging drinks. Rolling Sips, Desert Spirits, Liquid Caterers and Hey, Bartender! are just a few of the dozens of outfits that have popped up in recent years. Some, like The Hive (pictured), offer extras like custom drink charms and stirrers, photo booths, backdrops, catering and DJ services. Does your neighborhood bar offer all that? thehiveaz.com.
