Mylos

Mylos is the only restaurant on the Santorini caldera housed inside an actual working-era windmill, and once you step onto the terrace you understand why that architectural fact matters. The whitewashed cylindrical tower rises above the cliff edge at Firostefani — the quietest and most refined of the caldera villages — with a wraparound stone deck that aims the entire room at the volcano. Every table is a window seat. Every sunset is a proscenium.

The kitchen, led by chef Adam Kodovas, is the rare caldera operation that reads as a serious restaurant rather than a viewpoint with an adjacent menu. Kodovas works the crossover between refined Mediterranean technique and Asian precision — a style he has polished across multiple island seasons and one that positions Mylos well above the usual Firostefani fare. The sushi programme is the surprise: omakase-leaning nigiri, a disciplined sashimi list, and a short-but-serious selection of maki that rewards guests who arrive expecting Greek seafood and end up ordering Japanese instead.

The Mediterranean side of the menu holds its own. The braised short rib with smoked aubergine, the Santorini tomato with local burrata, and a handful of seasonal fish plates anchor a list that changes with what the caldera boats bring in. The seven-course tasting menu is the most efficient way to experience both halves of the kitchen at once — a fixed-price route that regulars consistently call the best value on the caldera cliff.

The name of the restaurant is only half true: Mylos bills itself as a champagne bar as well, and the cellar backs up the claim. Ruinart, Krug and Bollinger sit alongside a selected Greek-wine list that leans heavily on island Assyrtiko. Cocktails are built by a bar team that takes the form seriously. Expect a full dinner with wine at €120–€180 per person; sushi-only and champagne-only sittings at the bar run considerably less.

Mylos has picked up TripAdvisor Travellers' Choice Awards in consecutive years and is one of the small handful of Santorini tables where the service, food, view and wine all arrive on the same level. For a celebration, it is the easiest booking on the island to love. Cross-reference with the Santorini guide or compare to The Athenian House and 1800 Oia for alternative sunset-celebration rooms.

The birthday restaurant problem on Santorini is that the loudest, most obvious caldera tables tend to be the least interesting ones to eat at, while the serious kitchens often sit in back rooms without the view. Mylos solves both sides of that equation. The windmill terrace is the best sunset address in Firostefani, the service understands how to handle a birthday table (candles arrive at the right time; the champagne bottle is opened at the right pitch of drama), and the seven-course tasting menu means the guest of honour never has to navigate a menu while making conversation. For a birthday that wants to feel like the cover of a travel magazine, this is the best room on the caldera between Fira and Imerovigli.

Begin at the sushi counter with the chef's nigiri selection. Move to the seven-course tasting menu for the main sitting, or — if ordering à la carte — the braised short rib, the local sea bass, and the Santorini tomato and burrata opener. The champagne-paired dessert is the right finish. For sparkling, if the budget allows, open the Krug Grande Cuvée at course three; otherwise the Gaia Thalassitis is the smartest local pour on the list.
