6.4 Le Boeuf Sur le Toit, 34, rue du Colisee in the 8th, open 7/7, 01.53.93.65.55 (Metro: St-Philippe du Roule or FDR) has indeed been open since 1921 when the jazz era was in flower here, and moved to this location in 1941, during the occupation - so why go now, John? Well, it has a very young, new chef, Olivier Streiff, who was a "Top Chef" and the combo of old/new lured me.
I looked at the huge carte, decided today was not the day for oysters, so try the special lobe of foie gras - wow, perfectly cooked with, instead of a sweet chutney, a sweet and sour combo of pineapple and marinated raisins; which with my Saumur-Champigny, proved quite successful.
When I got the carte back to find a dessert, on the back page I found the Top Chef's brasserie and bistro "menu's", rather banal don't you think? Anyway, I went with the Baba "boeuf" (not beef at all but Boeuf sur le toit) which was adequate.
The tariff for two, with kind of day-old bread rolls, not worthy of an elegant place like this, no bottled water (only 1 of 10 tables had bottled ones), a bottle of wine and coffee, would be 105.60 E.
Go? Well, if you're my age, and French from the Ile de France, wanting a rather quiet (68.5 dB) and elegant place with inconsistent service (the head guy was terrific; the newby not so much) in the 8th, OK.
