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.

BOOKING PROCESS

From First Message to Event Day in Four Steps

Conference planning involves enough moving parts already. We make the coffee portion straightforward.

1. Send Us Your Event Details

Tell us your date, location, estimated headcount, and how many hours of service you need. Email, form, or text all work. Ben or Halle responds within minutes. We collect all the information we need in our quote form.

2. Review Your Quote

We confirm barista count, service duration, any add-ons, and travel fee if applicable. Our pricing is transparent and you will see the full number before committing to anything.

3. Confirm and Pay

We hold your date with a prepaid booking. For conferences with branding add-ons, we coordinate those details in the two weeks leading up to your event.

4. We Show Up Early and Handle Everything

On event day, you will usually be greeted by the same people you have been texting throughout planning. When we bring in additional help, that person has been trained directly by us. We arrive before your first attendees, run clean and efficient service throughout, 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.

Branding Add-Ons

  • Custom Cup Branding: $150

  • Custom Signature Drink: $100

  • Custom Cart Branding: $300

Branding add-ons require 2 weeks notice. Quantities confirmed at booking.

Menu Customizations

  • Reserve Espresso Upgrade

  • Specialty Drip Coffee / Cold Brew

  • Chai

Menu customizations are priced based on final guest count.

Frequently Asked Questions

Questions from conference and event planners we hear often.

  • Our pricing starts at $849 for one barista (covering 1 to 2 hours of service) and $1449 for two baristas. Multi-hour events are priced per additional hour beyond the base rate. A travel fee applies for venues outside our service area. Full pricing is published on our pricing page, so there are no surprises.

  • 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.
