Imagine that Dean & Deluca had a baby with Common Market, and you'll have a good idea about Earl's Grocery.
You can buy prepared foods (including duck leg confit, which I did not buy, but seeing it kind of blew my mind), beer & wine, artisanal bitters and other interesting ingredients for craft cocktails, everything you'd need to make a beautiful pasta dinner (including the freaking pot to cook it in), and more.
Then there's the coffee bar, bakery items (my friend brought some of their mini desserts to a recent gathering and they were a major hit), and a small but mighty made-to-order menu.
Earl's. Is. Awesome.
