Inexpensive, vest-pocket restaurants keep turning up in the most amazing places in Paris, and that’s great for all budget-conscious diners. Worth the detour is Katsuaki Okiyama’s latest venture, a tiny, “hole in the wall” steps from the Poissonière Metro in the 10th arrondissement . Carefully decorated on a budget – simple but pleasant hanging lamps, exposed stone walls, an efficient open kitchen – Abri  indeed shelters us from some of the expensive, mundane fare one might find elsewhere. The Japanese chef, trained with Robuchon and at Taillevent and Agapé Substance – offers simple, carefully prepared food, no surprises but no real disappointments either. Fresh, seasonal fare prepared right in front of you. What more could one ask? The 22-euro lunch menu offers a daily choice of either fish or poultry/meat as the main course,  with a no-choice starter, soup, and dessert. A first-course carpaccio of daurade (sea bream)(photo) was a feathery light, protein-rich starter, showered with paper thin slices of  fennel and radish, alas a bit too salty for even my salt-loving palate. Next, an alabaster soup arrived, almost like an angel, a delicate parsnip soup with a heavenly jasmine mousse, almost more of a dessert, but instantly appealing.  Main courses might include carefully seared and roasted duck breast, meaty and full-flavored, adorned by a light port reduction, garnished with ratte potatoes; or delicate lieu jaune (pollack, in the cod family) in a yellow tomato sauce. The sure star of the meal was the chocolate tart, a delicate layer of pastry topped with a thick and soothing ganache, paired with a light chocolate sorbet. When a simple café or wine-bar meal can easily cost way more than 22 euros, Abri is definitely worth the Métro ride, unless you live in the 9th or 10th, then walk!
