Plan your event
- Serves the Greenwich, CT area — confirm your venue is inside their travel range when you inquire
- Licensed & insured licensing and liability insurance come up in reviews or their own materials — still ask for a current certificate of insurance; most venues require one
- Dry hire you buy the alcohol, they bring the bar, the bartenders, and the service — the legal norm for mobile bartending in most states; they can usually send a shopping list sized to your guest count

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
We had an amazing experience with Peter from Wonderbarz! He did a fantastic job serving drinks, assisting with dinner service, and making sure everything ran smoothly from start to finish. Thanks to Peter’s professionalism and attention to detail, the host didn’t have to worry about a thing.
Peter and his team were more than 5 stars! They were polite, tidy, helpful, fun, sociable, had solutions, gave us a shopping list, made the most amazing drinks and we recommend them to any and everyone looking for a bartender/caterer!
I've had the pleasure of working with Peter for three very different events—a seated Italian dinner, a relaxed brunch, and a large cocktail party—and he exceeded expectations every time. From start to finish, Peter is a true professional.
We recently used Wonderbarz for an event and everything was absolutely outstanding! The food was fresh & beautifully presented. Our guests kept complimenting every dish throughout the evening. The staff was professional, friendly, and made the entire process stress free from start to finish.
Booking Wonderbarz for a wedding
Weddings come up for Wonderbarz — 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 Wonderbarz
Reviews and the service's own materials mention corporate events at Wonderbarz — 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.
