We are staying in the restaurant business with Sweetbitter, a novel in which a young woman moves to New York and finds a job in a fancy restaurant. The first half of the book is a well-researched description of the workings of high-end restaurants, with a heavy display of wine erudition. It’s not exactly gripping but it moves along tolerably. The second half descends into a tiresome and obviously hopeless love triangle. What a bore.
