London, United Kingdom · St. James's
An expert assessment built on data, context and gastronomic judgement.
Costas Spiliadis's London outpost brings his celebrated Greek seafood philosophy to a Grade II-listed building on Regent Street, where the spectacle begins at the market-style display of pristine fish flown in daily from the Mediterranean. The approach here is pure estiatorio tradition: exceptional ingredients, minimal intervention, letting the quality of line-caught whole fish, carabinero prawns, and Atlantic octopus speak for themselves through simple charcoal grilling and liberal dousing of Kalamata olive oil. This is luxury dining for those who understand that provenance and purity trump culinary pyrotechnics—a place where choosing your fish from ice is part of the ritual, and where Greek hospitality meets Mayfair polish.
Book the pre-theatre menu if you're headed to a show—it's a genuine three-course offering at a relative discount, not a truncated version, and the kitchen doesn't rush quality for speed.
Costas Spiliadis grew up in Patras, Greece, immersed in a food-loving family before studying at Concordia University and building what would become a global estiatorio empire rooted in a single philosophy: source the finest Mediterranean seafood and do as little as possible to it. His approach—born from Greek taverna tradition but executed with luxury-market standards—has earned recognition including The Concierge Choice Awards in International Cuisine and The Argo Award for Gastronomy. Spiliadis's influence extends beyond technique to sourcing networks that supply his restaurants with daily catches from Greek waters, maintaining consistency across continents through relationships with fishermen and an uncompromising eye for quality at the market.
Four dimensions, each assessed independently against the same criteria everywhere we rate.
The kitchen's strength lies in its restraint and sourcing, with whole fish grilled over charcoal to achieve clean, oceanic flavor rather than elaborate technique. Regulars consistently point to the chargrilled octopus as a benchmark—tender, smoky, perfectly balanced—while the raw preparations like salmon tartare with Greek yogurt showcase ingredient quality over composition. The vegetables, particularly the aubergine and zucchini, receive the same reverence as the catch, though seasoning can lean subtle for those accustomed to bolder Greek taverna flavors.
The energy sits firmly in refined Mediterranean luxury territory—lively without tipping into boisterous, with well-heeled regulars and pre-theatre diners populating the airy dining room. The Grade II-listed architecture lends gravitas, though the space maintains a warmth and approachability that feels more Athens than austere London establishment. Expect a buzz that builds through service, particularly around the fish display near the entrance, where the theatre of selection plays out throughout the evening.
The brigade operates with polished Greek hospitality, guiding guests through the market selection process and offering informed portion recommendations for whole fish priced by weight. Staff demonstrate genuine warmth and attentiveness, particularly with regulars who return for the consistency, though pacing can occasionally stretch during peak periods. The team's knowledge of both the catch and the Greek-focused wine list adds value, helping navigate the premium pricing with transparency about preparation methods and provenance.
Housed in a Grade II-listed building at the St James's end of Regent Street, the space balances architectural heritage with contemporary Mediterranean elegance—high ceilings, clean lines, and the dramatic market display of fresh fish and vegetables that anchors the entrance. The room feels spacious and light-filled, avoiding the clubby darkness of many Mayfair establishments, with sightlines that keep the open kitchen and grill in view. Tables near the seafood display offer theatre but can carry the briny scent of the catch—choose accordingly.
These four dimensions are a handful of the attributes we review. The Insider Rating also draws on research the compass does not display — among them the wine programme, the size and quality of the cellar, the location, and how long the house has operated. It is not an average of the scores above.
