A giant of the city’s cocktail scene and popular spot for burgers, shawarma and fries has served its last guests. Layla (4317 Manchester Avenue), the 10-year-old Grove restaurant and bar, has closed. A spokesperson for the restaurant who asked to remain anonymous confirmed the news to the Riverfront Times in a phone call yesterday afternoon, noting that the closure was technically being referred to as temporary, though the restaurant would likely never reopen.
