Mobile Espresso Bar for Private Events and Celebrations

Solarium Coffee brings a full espresso bar to your home, venue, or event space. Ben and Halle personally run every event, setting up a self-contained coffee cart with a La Marzocco espresso machine and single-origin beans from George Howell Coffee Company. Your guests get made-to-order lattes, cappuccinos, seasonal drinks, and house-made syrups. You get a vendor who handles everything from setup to cleanup.

How the Coffee Cart Works at a Private Event

The cart rolls into your space (living room, backyard, event venue, club house) and becomes the center of the gathering. Guests order whatever they want from the full menu. Every drink is made fresh by Ben or Halle. There is no limit on drinks per person.

The setup is self-contained. We bring the machine, the grinder, all cups and lids, milk (whole and oat), water, and our house-made syrups from our Framingham kitchen. We need one 15-amp outlet and about 6x6 ft of floor space. We arrive early to set up, we clean up completely when we're done, and we haul everything out. Nothing for you to coordinate on event day.

For outdoor events without power access, we can bring a generator. For rain or sun coverage, we offer a 12x12 ft tent as an add-on.

Events Where the Espresso Bar Shines

Birthday parties. A milestone birthday with great coffee instead of another caterer's boxed setup. Guests remember the latte with heart-shaped latte art more than the cupcakes.

Baby showers and bridal showers. The cart adds a polished, personal touch. Custom cups with the guest of honor's name or initials make it feel intentional.

Graduation parties. Celebrate with a menu that keeps the energy up for a full afternoon.

Holiday gatherings and open houses. Thanksgiving, Christmas, New Year's. Our seasonal menu (think Clovara in fall, Winterbloom in December) is built for these occasions.

Anniversary parties and milestone celebrations. A 50th birthday, a retirement party, a vow renewal. The espresso bar gives guests something to gather around.

Reviews

What our event planners and guests say about our coffee cart service:

★★★★★

I could not have asked for more professional, kind, thorough and attentive interactions with Solarium. They will not disappoint!

Karen, Private Event Host

★★★★★

Solarium was extremely friendly and professional and provided the most unique specialty coffee that we’ve ever had at one of our events. Can’t wait to work with them again.

Dom, Event Planner

★★★★★

The extraordinary, flavorful aroma and tasting of coffees at our large family gathering was provided by Solarium Coffee. A wide variety was offered, efficiently prepared and finished off with unique toppings, all done in a pleasant, professional manner.

Private Event Coffee Cart FAQ

  • Yes. Most of our private event bookings are at private residences. We need a 6x6 ft space, one 15-amp outlet, and ground-level access for roll-in. Garages, patios, living rooms, and backyards all work.

  • One barista serves approximately 50 drinks per hour. For events with more than 100 guests, we recommend two baristas. Not everyone orders at once, so our capacity typically exceeds the headcount comfortably.

  • No. Every booking includes unlimited drinks from our event menu for the full service window.

  • Matcha lattes, chai lattes, and hot chocolate are available as add-ons. These are popular for events with younger guests or non-coffee drinkers.

  • Two to three weeks is typical. Weekends fill faster than weekdays, especially in spring and fall. If you want custom cup branding, give us two weeks notice.

  • Ben and Halle. Always. The people you text with about logistics are the same people behind the cart at your party.
