Assassination Custard

Portobello's Smallest Stage

Kevin Street Lower sits on the southern fringe of Portobello, a neighbourhood that has become one of Dublin's more interesting patches for independent eating. The canal-side stretch runs through a mix of long-established local businesses and a newer wave of smaller, owner-operated rooms that have little interest in the conventions of formal dining. Assassination Custard belongs firmly to the latter category. The room holds three tables. That is not an approximation or a shorthand for intimate; it is the literal count. Walk past without knowing it exists and you almost certainly would.

That physical compression is the starting point for everything about the experience. Portobello has none of the institutional weight of St Stephen's Green or the tourist density of Temple Bar, and the restaurants that have taken root here tend to reflect that: lower overhead, higher creative latitude, an audience that comes specifically rather than stumbles in. Assassination Custard sits at an extreme of that tendency. The format is closer to a supper club operating out of a fixed address than to a conventional restaurant, and the room enforces a kind of focus that larger spaces cannot manufacture.

What the Format Signals

Across European fine dining, a split has opened between two distinct approaches to small-room cooking. One treats the compact space as theatre, using it to build a controlled, narrated experience where the room's limitations become part of the aesthetic. The other is simply a small room with good food. Assassination Custard sits in the first camp. Menus arrive written on brown paper bags, the kind originally made for penny sweets. The theatricality is not incidental; it is part of how the food is framed, and the framing matters as much as the plate.

That positioning places the restaurant in an interesting peer set. Dublin's dominant high-end rooms, Patrick Guilbaud and Chapter One by Mickael Viljanen, operate with full brigade kitchens, multi-course structures, and the infrastructure of classical fine dining. Glovers Alley and Bastible sit in a middle tier, where modern Irish cooking meets more formal service. Assassination Custard is not competing in any of those brackets. The comparison set is international and niche: small-room avant-garde operations where the cooking itself carries the argument, and where the absence of a conventional dining room is deliberate rather than a constraint. Internationally, rooms like Atomix in New York City and Le Bernardin in New York City represent different points on the spectrum of format-as-statement dining; Assassination Custard is making a different kind of argument at a different scale, but it is making one nonetheless.

Elsewhere in Ireland, the comparable ambition tends to surface in places with similarly unconventional structures. Liath in Blackrock, Aniar in Galway, and dede in Baltimore each operate with a strong authorial point of view and relatively small capacities. Bastion in Kinsale, Campagne in Kilkenny, and Terre in Castlemartyr represent the more formal end of Irish regional dining. Assassination Custard sits outside all of those registers. It is, in the most precise sense, a room doing something different.

The Cooking

The critical language around the food here is direct. The phrase used in documented recognition of Ken Doherty and Gwen McGrath's cooking — that it is "pulling the stars from the sky" — is not the measured hedging of a reviewer searching for something polite to say. Avant-garde theatricality is noted alongside the quality of the food, which positions this as a venue where conceptual ambition and culinary execution are treated as inseparable. The brown paper bag menus are the most-cited detail in coverage of the restaurant, but they function as a delivery mechanism for a menu that earns its own reputation independently of the packaging.

D'Olier Street represents another Dublin room working at the boundary of format and food. What distinguishes Assassination Custard within that broader Dublin conversation is the degree to which the constraints of the room have been converted into assets. Three tables in a cubicle of a space should feel like a compromise. The evidence suggests it does not.

Planning a Visit

The three-table capacity makes advance booking not merely advisable but arithmetically necessary. At any given service, the full complement of diners could fit in a large suburban kitchen. There is no walk-in culture here; the room fills on reservations, and given the attention the restaurant has attracted in its current iteration, booking well ahead is the realistic approach. Portobello is accessible from the city centre on foot or by a short bus or taxi journey; Kevin Street Lower is a direct address to reach from most central Dublin hotels.
