The New Generation of Jason Atherton Restaurants

Row on 5 (Savile Row)

Jason Atherton partnered with executive chef Spencer Metzger to launch Row on 5 on Savile Row in late 2024. Row on 5 stands out among active Jason Atherton restaurants, securing a rapid promotion to two Michelin stars in the 2026 Michelin Guide. A Michelin inspector noted that “there was a huge sum of work going into every detail, but what you saw on the plate was clean and uncluttered.”

The dining experience centers around a seasonal eight-course tasting menu priced at £245 per person, while the interactive Chef’s Table experience reaches £295. Premium wine pairings are handled by sommelier Roxane Dupuy, who won the Michelin Sommelier Award in 2026. Due to the high demand surrounding the two-star status, tables must be secured well in advance.

Chez Rose (Pollen Street)

When discussing upcoming Jason Atherton restaurants, Chez Rose represents the latest collaboration between Atherton and Metzger, scheduled to open its doors in early June 2026. Located at 5 Pollen Street in Mayfair, the concept shifts away from formal fine dining toward a relaxed French bistro format. The restaurant is named in honor of Metzger’s grandmother and highlights classic, accessible cooking.

In an interview regarding the launch, Metzger explained, “It is a meaningful restaurant, but we want it to be super relaxed. The dress code is going to be really chilled.” To avoid geographic confusion, diners should note that Chez Rose physically takes over the former Little Social site, rather than the larger building across the street that housed Pollen Street Social.

Sael & Three Darlings

For diners seeking casual Jason Atherton restaurants, Sael in St James’s Market offers a brilliant alternative. Opened in late 2024, Sael focuses on hyper-local British ingredients presented in a traditional brasserie layout. Meanwhile, Three Darlings in Chelsea provides a relaxed, neighborhood-focused dining setting that caters to families and casual weekend diners.

The Battle of Pollen Street: Chronicling the Turnovers

The physical footprint of the restaurant group in Mayfair shifted rapidly over a 24-month period. The closure timeline of these historic Jason Atherton restaurants reveals a massive portfolio pivot away from the older “Social” branding:

1. July 2024: The flagship Pollen Street Social closed permanently after 13 years of operation, as part of a wider portfolio reboot.

2. Late 2024: The original space briefly reopened as a casual pop-up concept named Mary’s, featuring a burger bar and grill.

3. February 2025: Mary’s ceased operations and closed for good, leaving the primary building vacant.

4. April 2026: Directly across the street, sister site Little Social quietly ended its own 13-year run to make way for immediate property renovations.

5. June 2026: The renovated Little Social space officially reopens under the new name and concept of Chez Rose.

Common mistake Callout: Many online booking platforms and older map applications still list legacy Jason Atherton restaurants as active choices. Always verify structural availability through the official Michelin Guide UK portal or direct reservation desks before coordinating your evening plans.

Other Notable Departures

The structural portfolio shift extended well beyond Mayfair. In July 2024, the group closed its long-standing Soho establishment, Social Eating House, after more than a decade of operations in the neighborhood. Additionally, public business listings via Companies House confirm that Social Wine and Tapas in Marylebone remains permanently closed. These rapid closures allowed the group to redirect its operational resources toward specialized partnerships and highly focused neighborhood concepts.

Logistical Booking Strategy

Logistical Booking Strategy

• Row on 5 (Savile Row): Expect extreme booking friction. Tables require a 6 to 8-week advance reservation via official channels due to the recent two-star Michelin upgrade. Highest price point (£245–£295).

• Chez Rose (Pollen Street): High initial demand due to launch window freshness. Monitor weekly booking drops for summer 2026 tables. Mid-tier pricing.

• Sael (St James’s) & Three Darlings (Chelsea): Moderate booking friction. Ideal for short-notice weekday reservations or casual business dining.

Logistical Pro Tips for Visiting Jason Atherton Restaurants

Planning a meal at one of these updated locations requires a few strategic adjustments. Use these practical insider tips to optimize your dining experience:

• Verify the exact street address: Map applications frequently lag behind real-world restaurant closures. Double-check that your destination is active so you do not arrive at a dark site.

• Request counter seating at Row on 5: When organizing your booking, ask for a seat at the open-kitchen counter. This gives you a direct view of Spencer Metzger’s culinary team preparing the tasting menu.

• Match your clothing to the restaurant style: Dress codes vary drastically across active Jason Atherton restaurants. Row on 5 maintains a formal atmosphere where tailored attire or jackets are preferred. In contrast, Chez Rose implements a casual policy with a relaxed dress code.

• Consult the sommelier at the flagship: Take advantage of the wine program at Row on 5, managed by Roxane Dupuy, who secured the Michelin Sommelier Award in 2026. The cellar features an extensive collection of Burgundy and grower Champagnes.
