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 found Maria's Mixers browsing on Instagram and I am so glad I did! My husband and I planned our own wedding. No coordinator or planner at all. In other words, lots of emails back and forth. Maria was responsive, helpful, and patient with all of my questions/requests. As for the day of team who handled the bar...
If you are looking for servers and bartenders that will make your event run smoothly, this is the place. This team shows up for you and your guests! I am a planner that values efficiency and I highly recommend this company.
As a Wedding Planner, Maria is beyond wonderful. Her team have gone above and beyond to make every wedding we have together just fabulous. Not to mention the food and cocktail are to die for! Highly recommeneded!
Amazing!!! The bar staff is so professional and friendly! They decorate the bar as well making it very fun to work with them. I hired them for my wedding and everyone loved them would gladly work with them again.
Booking Maria's Mixers for a wedding
Weddings come up for Maria's Mixers — 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 Maria's Mixers
Reviews and the service's own materials mention corporate events at Maria's Mixers — 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.
