Specialty Coffee Catering in Boston, MA
Give your Boston guests a coffee moment they will talk about on the way out.
Product launches in the Seaport, conference breaks at the Hynes, all-hands meetings downtown, birthdays in Beacon Hill. Coffee should be the easiest line on your run sheet. We bring a full espresso bar to your venue, make every drink to order, and handle setup, service, and breakdown while you run your event.
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. We are 30 minutes west in Framingham, we pour single estate espresso roasted in Massachusetts by George Howell Coffee Company, and we make our syrups from scratch.
MIT, Harvard, the Boston Red Sox, Levi's, Anthropologie, and FIFA have all had our cart at their events. Whether you are hosting 500 conference attendees or 15 people in a conference room, you get the same standard of service and the same coffee.

What We Do at Boston Events
Four ways Boston planners usually book us. The cart needs a 6x6 ft footprint and one dedicated 15-amp outlet, which nearly every office, hotel ballroom, and event space in the city can give us.
Corporate Events
The Seaport, the Financial District, Longwood, and the towers along Congress and State Street keep us busy with all-hands meetings, client appreciation events, and leadership off-sites. Quiet setup, fast service, and your logo on every cup if you want it.
Corporate coffee catering →Conferences and Expos
The BCEC and the Hynes run on tight break windows. Two baristas serve about 100 people an hour, and the cart tucks into a foyer without blocking traffic. We are happy to join the call with your venue coordinator about loading and power.
Conference and expo catering →Brand Activations and Pop-Ups
Newbury Street and the Seaport are Boston's busiest corners for activations. Branded cups, a signature drink named for your product, and cart branding in your colors turn the coffee line into the part people photograph. Outdoors, we bring a 12x12 ft tent and a generator.
Brand activation catering →Weddings and Private Celebrations
South End brownstones, Beacon Hill rowhouses, Jamaica Plain backyards, and Boston weddings from cocktail hour to the last dance. The cart fits in a home, a rented space, or a driveway, and our team runs the whole thing start to finish.
Private event catering →Espressos, americanos, cappuccinos, lattes, flat whites, matcha, and iced versions of all of it, plus guest favorites like Halle's Morning and the Cinnamon Sugar latte. Whole and oat milk are standard, almond with advance notice. Check out our menu →

How Booking Works
Four steps, start to finish.
Tell us about your event
Date, Boston venue, rough headcount, and how long you want us pouring. The form takes about two minutes and a price comes back in minutes.
Talk it through
You speak directly with Ben or Halle. If you are at a Seaport hotel or the Hynes and want to walk through loading and power first, that call is quick.
Lock in your date
A deposit holds your date, first come first served. Boston's conference calendar runs heavy in spring and fall, so those dates go early.
Enjoy your own event
We arrive before your first guest, run clean service throughout, and leave the space exactly as we found it. You will not have to manage us.
Boston Questions We Get a Lot
How much space and power do you need?
A 6x6 ft footprint and one dedicated 15-amp outlet. That covers the cart, a support table, and room for the baristas to work. We carry a 25 ft extension cord if we cannot be right next to the outlet. For loading we need ground-level entry or a freight elevator. Outdoors, we can bring a 12x12 ft tent and a generator so no outlet is needed.
Can you serve at the BCEC, the Hynes, or a Boston hotel?
Yes, and we have done plenty of events at comparable spaces. We carry liability insurance and can send a certificate of insurance to your venue or coordinator on request. One thing worth checking on your end: a few Boston venues have exclusive food and beverage arrangements that cover coffee. If you are not sure about yours, ask the coordinator and we will help with any documentation they need.
Is there a travel fee for Boston events?
No. Every Boston venue sits inside the travel area already covered by our package prices, so the number you see on the pricing page is the number you pay. If you are booking somewhere farther out, we quote travel up front rather than adding it later.
How far in advance should I book?
Two weeks of lead time is usually enough for weekday events and off-peak weekends. For Boston's spring and fall conference seasons, 4 to 8 weeks is a safer target, since we limit how many events we take in order to keep the quality up. That said, 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. You are not hiring an agency that sends whoever is free.
Can you brand the cups or create a drink for us?
Yes, and the signature drink and custom menu are free with every booking. We build the drink around your flavor profile, occasion, or product, and design the menu with your logo, colors, or names. Branded cups, a branded cart, and an on-drink logo printer are optional add-ons, and custom cups need about two weeks notice. Add-on prices are listed here →

Get Your Boston Quote in Minutes
Tell us your date, your venue, roughly how many guests, and which add-ons catch your eye. A price tailored to your event comes back usually within minutes, and Ben or Halle will follow up the same day.
