Book Your Holiday Party at El Barco: Private Buyouts & Taco Bar Catering in Back Bay
Yes. El Barco at 50 Dalton Street offers full and partial venue buyouts for holiday parties, corporate gatherings, and private events, with taco bar catering built around the same Mexican menu served on the regular floor. Groups can book anything from a semi-private section to a complete restaurant buyout depending on headcount and date.
Back Bay fills up fast every December, between office parties spilling out of the Prudential Center and holiday shoppers working their way down Boylston Street. El Barco sits right in the middle of that action, which makes it an easy stop for teams who don't want to trek across the city after a workday, and an easy landing spot for guests already downtown.
What does a venue buyout at El Barco actually include?
A buyout at El Barco means exclusive use of the dining room and bar, with the layout adjusted to fit your group — cocktail-style standing setups, seated dinners, or a mix of both. For companies searching for a venue buyout in Boston that doesn't feel like a generic event hall, the draw is that guests get the real restaurant: the same tile work, the same bar program, the same kitchen, just closed off for the party.
Smaller groups don't need to take over the whole space. El Barco can section off part of the dining room for parties that don't require a full buyout, which keeps things flexible for a 20-person team dinner versus a 150-person company-wide celebration.
What's on the taco bar catering menu?
The taco bar setup lets guests build their own plates from a spread of proteins, tortillas, salsas, and toppings, served buffet-style so a large group can move through the line quickly without a sit-down service delay. It's the format most holiday parties gravitate toward because it keeps the room moving and gives guests with different tastes — or dietary needs — options without a lot of back-and-forth with servers.
For companies researching taco bar catering in Boston for an office party, the appeal is straightforward: it reads as an event, not just a meal. Guests build their own tacos, refill their own margaritas, and the room stays loose instead of stiff.
"People remember the taco bar more than they remember the PowerPoint," is the kind of feedback the team hears after corporate parties — informal, but it's the whole point.
Is there a bar program for holiday parties?
Yes, and it's a real part of the draw. El Barco runs a full tequila and mezcal program alongside its margaritas, so a holiday party can build a drink package around house margaritas, a tequila flight station, or a simple open bar for beer and wine. Boston has no shortage of places calling themselves a tequila bar, but at El Barco the agave spirits list isn't an afterthought bolted onto a taco menu — it's built to pair with the food, which matters when you're planning drinks for fifty people who all want something different.
How far in advance should you book?
Holiday dates in Back Bay book out weeks ahead, especially Thursday and Friday nights in December when Prudential Center and Copley-area offices are all trying to lock down the same handful of prime slots. El Barco is open seven days a week, with late hours Friday and Saturday until 1am, which gives planners more flexibility on timing than venues with tighter weekend hours — but the popular weeknight and Friday slots still go first.
Anyone weighing a December date should reach out early and have a headcount range ready, even a rough one, since that number drives whether a full buyout, partial buyout, or standard large-party reservation makes the most sense.
What size groups does El Barco accommodate?
El Barco handles everything from a 15-person team lunch to a full-restaurant buyout for a company-wide party. The flexibility comes from the space itself: a bar area that works for a mingling cocktail hour, and a dining room that can be set for seated service or opened up for the taco bar line.
For teams still deciding on format, it's worth reading through El Barco's take on group dining in Back Bay or browsing the full menu rundown before locking in a headcount.
Why book a Mexican restaurant instead of a hotel ballroom?
A restaurant buyout gives a holiday party actual character instead of a beige function room. At El Barco, that means real tacos coming off a working kitchen line, a tequila and mezcal list guests can ask questions about, and a room that already has energy in it every other night of the week. It also tends to be less rigid — no minimum room rental separate from food and drink, no banquet-hall paperwork.

How do you get started booking?
The fastest way is to contact El Barco directly at 50 Dalton Street with a proposed date, headcount, and whether a full buyout, partial buyout, or standard reservation fits the group. The events team will work from there on menu format — taco bar, seated, or a hybrid — and bar package.
Back Bay holiday calendars fill in fast, and the restaurant's central location near Prudential Center and Boylston Street makes it one of the easier venues for out-of-town guests and coworkers alike to find. For teams still comparing options, it's worth a look at how other Boston groups have used the space for private events before the December calendar locks up entirely.
