Bottomless lunches at Bistro Grenier, Saturday to Sunday. A table of two, or a gathering of nine. For birthdays, hens, or simply an excuse to linger. $99 per person includes free-flowing Hugo Spritz and bottomless bubbles that accompany a lunch. House-made bread with butter, crudités with buffalo curd, chicken liver pâté set under a soft verjus jelly, and a Salade Lyonnaise with duck, bacon, and poached egg. Then, a vol-au-vent filled with Ruffle Farm mushrooms and red wine, and pommes frites to share. A lunch designed to stretch into the afternoon, as all good ones do.
