Boston Coffee Catering & Mobile Coffee Cart
Serving Boston, Cambridge & MetroWest, MA
You're planning something that matters: a corporate event, conference, brand activation, or wedding. The last thing you need to worry about is the coffee. That's our job, and we’ll make sure coffee is the easiest part of your whole planning process.
Solarium Coffee brings a full espresso bar to your event, anywhere in Greater Boston or MetroWest. Your guests get handcrafted lattes, cappuccinos, and hand-whisked matcha made to order. You plan your event directly with the owners, Ben and Halle, and on event day you'll usually find one of them behind the cart.
Trusted by Leading Organizations Across Greater Boston
Organizations like MIT, Harvard, The Boston Red Sox, Levi's, Anthropologie, and FIFA trusted us with their events, and here's what that means for you: whether you're hosting 500 conference guests or 15 friends in your backyard, you get the same owner-level attention and the same coffee. You'll plan every detail directly with Ben and Halle, and your event gets their full attention regardless of its size or scope.
A Full Coffeehouse Experience From Our Mobile Coffee Cart & Espresso Bar
Great coffee does real work at an event. It draws people in, keeps them there, and gives them something to talk about. Our mobile espresso bar delivers that without adding anything to your to-do list: we handle setup, service, and breakdown while you run your event.
Every drink from our mobile espresso bar is made on-site by skilled baristas using single estate coffee roasted right here in Massachusetts, with syrups we make from scratch. The classics are all here, and so are signature and creative seasonal drinks your guests won't find anywhere else.
A Mobile Espresso Bar for Whatever You're Planning
Hosting 20 colleagues or 500 attendees? Either way, we arrive with our custom-built cart, a high-end espresso machine, and house-made syrups. You point us to a corner; we handle everything from setup to last cup.
Want your team and clients to feel genuinely appreciated? Nothing says it like a barista making their drink, their way. From all-hands meetings to holiday parties, we bring the café to your office.
Your attendees stay sharp, your breaks become a highlight, and you never think about the coffee line or if coffee will run out. We handle high-volume espresso service smoothly so you can focus on running your event.
From cocktail hour through the last dance, your guests sip handcrafted drinks from a cart that photographs beautifully. Add custom cups and a signature drink named after the two of you.
Birthdays, baby showers, anniversaries, backyard parties. We set up easily in your driveway, patio, or living room, and every guest leaves with a memorable treat and a story.
Give your shoppers a reason to stop, stay, and share. Our cart draws foot traffic, extends dwell time, and creates the in-store moment people post about.
Your brand on the cart, your logo on every cup, a signature drink built around your identity. Your guests fall in love with your brand one latte at a time.

How to Book Our Coffee Cart
Event planning involves enough moving parts already. We make the coffee portion straightforward.
1. Tell Us About Your Event Share your date, location, headcount, hours of service, and event type. Email, form, or text, whatever's easiest for you. Ben or Halle will get back to you the same day, usually within minutes. Our quote form collects everything in one go.
2. See Your Full Price Up Front We confirm your barista count, service hours, add-ons, and any travel fee, so you see the complete number before committing to anything. Plans change? Ours can too. Tell us what shifted and we'll do our best to accommodate it.
3. Lock In Your Date A 50% deposit holds your date (we book first-come, first-serve). If you've chosen branding add-ons, we'll work out those details with you in the weeks before your event.
4. Show Up and Enjoy Your Own Event On the day, you'll usually be greeted by the same people you've been texting all along. When we bring in additional help, it's a trusted barista trained directly by us, so the quality never changes. We arrive before your first guests, run clean and efficient service, and leave your space exactly as we found it.

Frequently Asked Questions
Check out our full list of our coffee catering FAQs.
-
All we need from you is a 6×6 ft area and a dedicated 15 amp outlet. That space covers our cart, a support table, and room for our baristas to work. We have a 25 ft extension cord if we can’t be right next to an outlet. We take care of everything else — water, cups, lids, coffee, matcha, whole and oat milk, house-made syrups, and trashcans. For outdoor events, we can also bring our own 12×12 ft tent and a generator so no outlet is needed.
-
Yes, absolutely! We have done many outdoor events. If needed we have a 12 ft x 12 ft tent we can bring and a generator to power our equipment if an outlet is not available outdoors. Check out our gallery to see both indoor and outdoor setups.
-
We charge per hour of service. Every service package is fully inclusive of the cost of our baristas, equipment, travel fees, and supplies like coffee, matcha, cups, lids, whole and oat milk, and house-made syrups. Additional customizations are available to make your event unique if desired. You can see all our available add-ons and their pricing in our instant quote form.

Solarium Coffee is a coffee shop on wheels. We serve the classics like espressos, americanos, cappuccinos, and lattes. We also have guest favorites like the Halle’s Morning and the Cinnamon Sugar and a non-coffee option of matcha. Every season we also rotate our seasonal menu items. Check out our coffee catering menu to see them!
-
As soon as you know your date, reach out. We limit our availability to maintain quality, and popular dates fill up. Two weeks of lead time is typically enough for weekday events and off-peak weekends, but peak season weekends book further out. That said, we always try to accommodate last-minute requests, so don't hesitate to reach out even if your event is close.
-
We serve corporate events & conferences, weddings, private events, retail pop-ups, brand activations, fitness & wellness events, teacher appreciation & PTO events, recurring service as a resident amenity, and Cars & Coffee events. If you have an event type not listed here, still feel free to reach out and we can work out the details to service your coffee catering needs.
