Boston Coffee Catering & Mobile Coffee Cart
A full espresso bar at your event, anywhere in Greater Boston and MetroWest. Coffee becomes the easiest part of your planning.
Trusted by Leading Organizations Across Greater Boston
MIT, Harvard, the Boston Red Sox, Levi's, Anthropologie, and FIFA have all had our cart at their events. Whether you host 500 conference guests or 15 friends in the backyard, you get the same owner-level attention and the same coffee.
A Full Coffeehouse Experience From Our Mobile Espresso Bar
Conferences, brand activations, corporate events, and weddings across Boston and MetroWest. We bring a full espresso bar and handle setup, service, and breakdown while you run your event.
Every drink is made on-site by skilled baristas using single estate espresso roasted in Massachusetts by George Howell Coffee Company, with syrups we make from scratch. The classics are all here, plus hand-whisked matcha and seasonal drinks your guests will not find anywhere else.
Solarium is owner-led. Ben and Halle plan and coordinate every event, and most of the time they are behind the bar too, alongside a team of baristas they trained themselves.

Client Testimonials
★★★★★
“What a big difference it made having Ben and Solarium Coffee at our multi-day meeting in Boston. Coffee may seem like a small thing but our attendees were 80 % international and loved having the personal touch of having a coffee cart (instead of just gallons of hotel coffee) with us throughout the day. Solarium was exactly what I was looking for: personally owned, so easy to work with, attentive and personality that engaged our guests. … If we are ever back in the Boston area I would hire Ben and Solarium Coffee in a heartbeat !!”
JoeCreative Director
★★★★★
“I can’t say enough great things about Solarium Coffee! We had them come out for a staff appreciation event, and the entire experience was absolutely fantastic from start to finish. They were on time, professional, easy to work with, and the service was impeccable. The drinks were absolutely delicious, and they even created a special signature drink just for our event, which everyone loved! … The pricing was very reasonable, and the entire experience exceeded my expectations. … I will absolutely be reaching out to them again in the future.”

How to Book Our Coffee Cart
Event planning has enough moving parts. The coffee part takes four steps.
Tell us about your event
Date, location, headcount, hours, and event type, by form, email, or text. Ben or Halle replies the same day, usually within minutes.
See your full price up front
We confirm baristas, hours, add-ons, and any travel, so you see the complete number before committing. Plans change? Ours can too.
Lock in your date
A 50% deposit holds your date, first come first served. Branding add-ons get worked out with you in the weeks before.
Enjoy your own event
We arrive before your first guest, run clean service, and leave the space as we found it. You will not have to manage us.
Frequently Asked Questions
What do you need to set up at my event?
A 6x6 ft area and one dedicated 15-amp outlet. That covers the cart, a support table, and room for our baristas to work, and we carry a 25 ft extension cord. We bring everything else: water, cups, lids, coffee, matcha, milk, syrups, and trash cans. Outdoors, we can bring a 12x12 ft tent and a generator so no outlet is needed. See indoor and outdoor setups in our gallery →
How is your service priced?
Flat packages by guest count, published above. Each covers 2 hours of service, the baristas, equipment, and every supply on the included list. Extra hours and branding add-ons are priced up front. Inside our service area there is no travel fee, and farther out we quote travel before you book, never after.
What is on your menu?
The coffee shop classics, plus matcha. Espresso, americano, cappuccino, and latte, guest favorites like Halle's Morning and the Cinnamon Sugar, and a rotating seasonal menu. See our coffee catering menu →
How far in advance should I book?
Two weeks is usually enough for weekday events and off-peak weekends. Peak season weekends book 4 to 8 weeks out, since we limit how many events we take to keep the quality up. Reach out even if your date is close. We often make it work.
Who actually shows up on the day?
A Solarium barista team, usually with Ben or Halle behind the bar. Ben and Halle coordinate every event and work most of them in person. On larger events, or days with more than one booking, our baristas run the bar, all trained by us to the same standard. We carry liability insurance and can send your venue a certificate on request.
What types of events do you serve?
Almost any event with guests who like coffee. Beyond the six above, we serve productions and on-set crews, fitness and wellness events, teacher appreciation and PTO events, recurring resident amenity service, and Cars and Coffee events. Not listed? Ask anyway.
