L'Éclair de Génie

One pastry, carried further than usual

The éclair case is the reason to walk in. This is a Paris boutique built on a single form: choux baked long, filled, glazed and finished, then repeated in enough versions to turn a familiar pastry into a collection. Christophe Adam opened the house around that idea, and the counter has held to it since.

The narrowness is the point. A classic éclair can disappear into habit, ordered without much thought at the end of a meal; here the pastry is the whole proposition, presented as a bright object in a row of them, with the glaze doing as much work as the cream underneath. Seasonal flavours rotate through the case, so the display changes more often than the format does. Chocolate work sits alongside, in truffles and small pieces, but nothing is allowed to crowd the éclairs out.

A counter with a few seats

The room works by the case. Service is counter-led, and the decision happens standing up with the éclairs in front of you, which is a faster way to choose than reading a menu. A small tea salon gives you somewhere to eat one on the spot rather than carrying it through the afternoon.

The decor is contemporary and deliberately clean, which suits pastries that are visual before they are anything else. This is not a long lunch or a full pastry counter with every traditional category represented; it is a short, precise stop. Relais Desserts membership places the house among the French pastry names held to a common standard, which is serious company for a boutique built on one shape.

Start with the case, not a flavour

The best approach is to arrive without a fixed order and choose from what is in front of you. The house rotates its flavours, so the éclair that defines one visit may not be there on the next, and the display is arranged to be read that way.

If there are two of you, take one chocolate-led éclair and one fruit-led one, since that comparison shows the range better than two of the same. Chocolate truffles are the thing to add when the éclair alone is not enough, and they travel better through an afternoon. Then use the tea salon if you want to slow the visit down, or take the box and keep walking; the counter is built for both.
