Booking basics
Mobile bartenders book by the date, not the walk-in — popular Saturdays (especially May–October) go months out, so inquire early with your date, venue, guest count, and whether you want a full package or dry hire. Most will hold a date with a deposit and a signed agreement.

From the reviews
I was so happy to have found Mike Heitzler and "Pearl," his horse trailer bar for my daughter's wedding venue on a working horse ranch in Fort Collins. Mike took the time to answer all my questions about keg sizes and what would fit in the bar. He also offered to write up the liquor order for the wedding.
Mike and Kate are so great to work with, and Pearl (their nickname for the mobile bar trailer) has a nice rustic, minimalist look that makes it super easy to decorate and customize. Their pricing is really reasonable, too. Highly recommended!
Pearl is the cutest addition to any party or wedding! Use her to keep kegs cool and on tap or turn her around for a full service bar! Adorable, functional and portable! Who could ask for more?!
What a fun way to spice up any event. I've had such great experiences working with On The Rocks and highly recommend them to add something unique to your party!
Booking On the rocks for a wedding
Weddings come up for On the rocks — confirmed on their own site, so they'll know the rhythm of the day: cocktail hour hits all at once, then the bar settles into a steady hum until the last dance. Two numbers get your quote right. First, the staffing math: the standard rule is one bartender per 50–75 guests — so a 150-guest wedding usually means two to three bartenders, and going thin here is the classic cocktail-hour line mistake. Second, drinks per guest: plan on roughly two drinks in the first hour and one per hour after; a dry-hire bartender can turn that into an exact shopping list for your headcount so nothing runs out and nothing goes back to the store.

Corporate events with On the rocks
Reviews and the service's own materials mention corporate events at On the rocks — holiday parties, launches, client mixers. For office events, three things are worth settling on the first call: whether they carry the liquor liability insurance your building or venue requires, whether they can run a mocktail or zero-proof menu alongside the bar, and how invoicing works if your company needs a W-9 and net-30 terms.
