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.

On The Rocks Mobile Bartending exceeded all of my expectations! From start to finish, they were incredibly professional, communicative, and detail-oriented. Their team brought an impressive level of knowledge about spirits, offering unique insights into their craft cocktails, which were absolutely delicious.
Details, details, details!! On the Rocks Mobile takes bartending to the next level! Sharece (the owner), is absolutely phenomenal— she is professional, timely & engaged! We used this mobile service for a party & it was beyond perfect.
On the Rocks was bartending at a networking event I attended. I was blown away by how beautiful the bar set up was and loved the detail she put into the drinks down to the garnishes that matched the theme of the event. The drinks tasted delicious! I still think about how good they were.
Booking On the Rocks Mobile Bartending Company for a wedding
Weddings come up for On the Rocks Mobile Bartending Company — 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 Mobile Bartending Company
Reviews and the service's own materials mention corporate events at On the Rocks Mobile Bartending Company — 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.
