"It's garlicky, it's yummy." That's how Gabriela Guitron, the head chef building the opening menu for LPM Restaurant & Bar, describes the escargot her kitchen has been rehearsing for weeks. The snails are pan-seared, baked in butter, roasted again, and delivered to the table in a metal tray built with a circular hole for each shell. A crusty baguette rides along for mopping duty. It is, by any measure, a small and specific dish. It is also the clearest signal yet that the second floor of the Four Seasons Hotel One Dalton Street has quietly become the most interesting stretch of real estate in Back Bay for anyone deciding where to eat on a Tuesday.
LPM opens September 24 in the space at One Dalton, an 80-seat dining room bringing the brand's French Riviera concept to the Northeast for the first time. If you live within walking distance of Dalton and Belvidere, this is not background noise. It is the third full restaurant concept the building has stacked into the same footprint since 2019, and each one has arrived without displacing the others. That pattern is worth paying attention to, because it tells you something about how this particular block of Back Bay is being used that a single restaurant opening never could.
The Room That Used to Serve Brunch
LPM isn't new construction. It's a reimagining. The space belonged to One + One, the hotel's brunch concept and, according to the property, Boston's only luxury brunch buffet, with a New England-inspired raw bar and handmade pasta service on weekends. That room is being gutted and rebuilt into what the brand calls a design-forward, sunlit oval dining space with Belle Époque influences, the same architectural language LPM uses at its other locations from London to Dubai.
The decision to convert a breakfast room into a dinner destination rather than build new tells you something about how tight the building's second floor already is. Four Seasons didn't expand. It swapped one concept for a different one in the same square footage, which means the hotel is betting that Back Bay diners will fill an evening restaurant more reliably than they filled a Sunday brunch buffet. LPM's own leadership frames the move as market logic rather than real estate logic: CEO Nicolas Budzynski has pointed to Boston's seafood supply chain as the specific draw, following the brand's earlier US launches in Miami and Las Vegas.
Two Floors, Three Kitchens
Here's the part a Back Bay resident actually needs mapped out. LPM and Zuma share the second floor. Zuma, the Japanese izakaya-style restaurant and bar, has been there since the hotel opened in 2019 and remains the twelfth location in Zuma's international portfolio, alongside outposts in London, New York, and Miami. It runs on shared plates from three open kitchens, a sushi counter, and a robata grill, built around the informal, no-particular-sequence style of Japanese pub dining.
Trifecta sits one level down, at the lobby. It's the cocktail lounge that does double duty as an afternoon tea room on weekends and a New England coastal dinner spot at night, with a menu that includes a Surf & Turf Burger, langoustine tagliatelle, and a seafood platter built around Island Creek oysters. Trifecta's dinner service runs daily from 4pm, with weekend tea seatings around midday for anyone who wants scones and Champagne before the evening crowd arrives.
That means one address now runs three unrelated kitchens on two floors: a Japanese izakaya, a New England lounge, and, as of late September, a French Riviera dining room built around Mediterranean produce and fresh seafood. None of them compete for the same reservation. A date night at LPM, a client dinner at Zuma, and a Sunday tea at Trifecta are three different plans that happen to use the same elevator bank.
What You're Actually Ordering
The LPM menu leans into the brand's Côte d'Azur identity rather than reinventing it for Boston, though Guitron has built in a handful of city-specific plates, which is standard practice across LPM's other locations. Reported highlights include:
- A wagyu tomahawk steak served with potato galette and Bordelaise sauce
- Classic duck à l'orange with grilled cabbage
- Salt-baked sea bass with artichokes and tomatoes
- A burrata salad with imported Italian cheese, cherry tomatoes, and basil
- A green lentil salad with sliced apple and torched cherry tomatoes, which Guitron describes as a refreshing opener built on the acidity of the apple and vinaigrette
- Caviar service with the traditional crème fraîche, red onion, caper, and brioche trimmings
- Breakfast options including an omelet with sautéed leeks, confit Maine lobster, and Osietra caviar
Guitron's approach, by her own description, is to keep the plate simple enough that the ingredients do the talking. That's consistent with how LPM operates across its international locations, from London to Dubai to Hong Kong, where the format stays largely fixed and each city gets a small window to localize.
The Walk Between Reservations
None of this changes anything about buying or selling in Back Bay. It does change what a Tuesday night looks like for the people who already live here. One Dalton is a five-minute walk from the Christian Science Plaza and sits close enough to Newbury Street, the Prudential Center, and Copley Place that most residents already pass it on the way to somewhere else. Now that walk has three separate reasons to stop.
The building itself is part of the story. At 724 feet, One Dalton is the tallest residential building in New England and the third tallest structure in Boston, with 160 Four Seasons private residences stacked above the hotel floors. The dining program below those residences has been built incrementally rather than all at once: Zuma opened with the hotel in 2019, Trifecta relaunched its dinner concept and cocktail menu more recently, and LPM is the newest layer, replacing rather than adding. That incremental pattern is easy to miss if you only notice the newest headline. Taken together, it means Back Bay now has a single building where three genuinely different dinners are each other's neighbors, not their competition.
If you're weighing a move into Back Bay, or already own here and are curious what the neighborhood's day-to-day texture actually looks like beyond the brownstones and the Public Garden, this is the kind of detail worth knowing. It's a small, specific thing. It's also exactly the kind of small, specific thing that tells you a neighborhood is still being actively built out, not just maintained.
