Built for High-Volume, High-Stakes Events

Conferences and expos run on tight schedules. Breaks are short, lines form fast, and attendees remember a bad cup of coffee just as well as a good one. Solarium Coffee is set up specifically for high-throughput service: an espresso machine, experienced baristas who move with purpose, and a menu that is simple enough to execute quickly without sacrificing quality.

We have served events ranging from 25-person boardroom summits to multi-day events to expos with several hundred attendees. Whether you need one barista for a half-day breakout or two baristas running back-to-back sessions across a full conference day, we scale to your program.

✓ We bring everything. Espresso machine, grinder, coffee, matcha, all cups and lids, milk and oat milk, serving equipment. Nothing to source or coordinate on your end.

✓ We arrive early. We are dialed in and pulling shots before your first session starts.

✓ We clean up completely. We leave your venue exactly as we found it.

WHAT SETS CONFERENCE SERVICE APART

Not All Catering Coffee is Conference-Ready

Most conference coffee is a hotel urn that was brewed two hours ago. Here is what Solarium does differently.

⚡

Speed Without Shortcuts

Our baristas are trained for volume service. We move efficiently. Every drink is still pulled fresh to order, not pre-batched or sitting in a thermos. Our menu is designed to make it easy to craft a variety of high quality drink options quickly.

☕

Specialty Coffee, Not Hotel Coffee

We source single-producer beans from some of the world’s most respected roasters. We bring our house-made seasonal and signature syrups to every event too. Attendees notice the difference immediately, and they talk about it.

✦

A Brand Moment, Not Just a Beverage

Custom cups printed with your event or sponsor logo, a signature drink named for your conference theme, and a fully branded cart are all available. Check out our gallery.

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. 

CUSTOM BRANDING

Turn the Coffee Cart Into a Conference Asset

Conferences live and die by their details. A coffee station is a natural gathering point during every break. With a few add-ons, it becomes something people photograph, share, and remember.

We offer custom cups with your event logo or sponsor mark, a bespoke signature drink named for your conference, and full cart branding with your graphics. All of these are available with two weeks notice.

For events with a sustainability or sourcing story to tell, our reserve espresso upgrade sources from a traceable single-producer lot from specialty roasters. It is a specific, credible detail that resonates with audiences who care about where their food and drink comes from.

I tried Solarium at a work conference, and their coffee was so refreshing-- creative and original flavors.

The most unique specialty coffee that we've ever had at one of our events

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.

Joe

❞

From day one, Ben was incredibly responsive, flexible, and easy to work with.

Solarium offered a variety of custom branding opportunities (including custom cart wrap and branded cups) that really elevated the offering and allowed us to seamlessly incorporate it into the event experience.

Frequently Asked Questions

Questions from conference and event planners we hear often.

  • Full pricing is published on our pricing page, so there are no surprises. Multi-hour events are priced per additional hour beyond the base rate. A travel fee applies for venues outside our service area.

  • Yes. With two baristas running simultaneously, we can serve roughly 100 guests per hour. For conferences where the full attendee count is not in line at once (which is typical during breaks), this covers events well into the 300 to 400 range. We can discuss your specific break schedule and expected traffic patterns to recommend the right configuration.

  • We do. Multi-day events are priced per day of service. Get in touch with your event dates and we will put together a quote for the full run.

  • Access to a standard electrical outlet and a small footprint for the cart (roughly 6 by 6 feet). We do not require a dedicated water line. We bring our own water supply for standard service.

  • We recommend reaching out at least three to four weeks before your event, especially if you want branding add-ons, which require two weeks notice. That said, we accommodate shorter timelines when our calendar allows. It is always worth asking.

  • We serve conference and expo venues across Boston (Financial District, Seaport, Back Bay, Downtown Crossing), Cambridge (Kendall Square, Harvard Square), Newton, Brookline, Somerville, Lexington, Concord, Waltham, Needham, Framingham, Natick, Dedham, Quincy, and surrounding communities.

  • Yes to both. We carry oat milk as a standard dairy-free option and can accommodate decaf requests. Let us know your audience profile when you book and we will plan accordingly. We always bring a handful of decaf servings. If you expect decaf to be a popular option, we recommend adding the Decaf Espresso add-on to your service.
