JW Marriott Grosvenor House London Celebrates Renovated JW Steakhouse & Bourbon Bar, Introducing New Dining and Bourbon Experiences for 2026
Mayfair’s five-star luxury hotel, JW Marriott Grosvenor House London, has unveiled the refreshed JW Steakhouse and Bourbon Bar following a recent multimillion-pound refurbishment, marking a new chapter for Park Lane’s long-established all-American steakhouse.
Building on the redesign, the restaurant and bar will introduce a year-long programme of themed menus, bourbon tastings and masterclasses throughout 2026, giving guests new reasons to return while reinforcing its reputation as one of Mayfair’s go-to destinations for steak and bourbon.
A New Era for an American Classic on Park Lane
The refreshed interiors draw inspiration from classic American steakhouses, with dark wood panelling, rust-coloured furnishings and intimate booths creating a warm, relaxed setting. Checkerboard flooring and carefully considered lighting reference early 20th-century New York, while butcher-style blackboards displaying daily selections highlight the restaurant’s focus on quality ingredients and craftsmanship.
American Steakhouse Favourites Led by Executive Chef Patrick O’Sullivan
Executive Chef Patrick O’Sullivan leads the kitchen, drawing on experience gained in both London and San Francisco. Since his appointment in 2025, he has shaped a menu grounded in American steakhouse classics, built around carefully sourced produce including premium USDA cuts from Creekstone Farm in Kansas, alongside Australian Wagyu and selected UK-reared beef.
Signature dishes include Maryland‑style crab cakes, baked Orkney scallops and a towering seafood platter of lobster, crab, jumbo shrimp and oysters. Beyond steaks, comforting classics such as braised Angus short ribs, grilled jumbo shrimp and blackened salmon broaden the menu’s appeal. No visit is complete without the iconic JW Cheesecake, served more than 40,000 times each year and a firm favourite among both regular guests and newcomers.
One of the Largest and Rarest Collections of Bourbon Outside of the States
The Bourbon Bar stands out with a bespoke cabinet crafted from reclaimed barrels, displaying over 500 rare and vintage bourbons – including exclusive and pre-Prohibition bottles – curated by in-house expert Robert Sreter. As the largest collection outside the US, guests can discover unique pours through tastings, masterclasses and menu pairings offered throughout the year.
Alongside neat pours and flights, the bar also serves a roster of bourbon‑based cocktails, championing the spirit’s versatility across smoky, spiced and modern interpretations. Guests can reserve and store their own labelled bottle for future visits, while the Old Fashioned Trolley, created in partnership with leading American distillery Buffalo Trace, brings added theatre with personalised aged or smoked Old Fashioneds served tableside.
New Menus, Tastings and Seasonal Dining Experiences for 2026
To build on the recent refurbishment and pay homage to its American heritage, JW Steakhouse and Bourbon Bar will host a series of tastings, masterclasses and limited-time menus throughout 2026. Seasonal menus and dishes inspired by regional American flavours and occasions including Independence Day and Thanksgiving will feature heavily, and during warmer months, themed dining experiences will extend onto the JW Garden terrace overlooking Hyde Park.
General Manager, JW Marriott Grosvenor House, Stuart Bowery, said:
“The refurbishment of JW Steakhouse and The Bourbon Bar reflects our ongoing commitment to evolving the guest experience at Grosvenor House. These spaces now feel even more connected to the hotel’s heritage while offering the comfort, craft and atmosphere today’s guests value. The new programme of dining and bourbon experiences gives both returning guests and first-time visitors fresh reasons to visit Park Lane.”
