It’s traditional to allow a new opening a few weeks to get up and running before going in to review. This gives them time to work out any kinks before they’ve opened “officially.” Which would be all well and good if they weren’t, you know, still officially accepting currency for their services in the meantime. That courtesy mostly applies to the food side of things anyway; a kitchen is a tricky beast with a lot of moving parts and a lot of new dishes to learn. A bar, on the other hand, is a bar, and the staff has presumably been making these cocktails at other bars for years. In the case of Sterling’s — the brand new State Street “cocktail bar” and restaurant — presumably at one of the Glynn Group’s many other properties like Dillon’s, Clerys, or Granary Tavern.
