Time to put those rumors about the restaurant that will replace Pops in the South End to bed: Chowder reports that Kitchen plans to open there as soon as the end of this month or by early June. The new restaurant comes from Scott Herritt, who runs Marliave and Grotto, and will feature historically-inspired cuisine like Tournedos Rossini, a hearty stew from the mid-1800?s, and Indian pudding, revisited. Of course there will be antiquated cocktails aplenty, conduits for ever popular bitters. From the sound of it, Kitchen will take existing trends like comfort food and regional cuisine to the next level by backing them up with soundly researched recipes from yesteryear. Earlier, the restaurant was thought to be called Smithfield Kitchen. Other venues celebrating historic foods include the upcoming Tavern & Tea Room at the new Tea Party Museum and Cafe G at the Isabella Stewart Gardner Museum.
