Funny, I just got out of their parking lot. its basically 3-4 whole grocery stores and a warehouse all together.
I don't drink alcohol myself, but the alcohol department is the size of a grocery store on its own with booze from all over. Aisles upon aisles of wine and beer, and a backroom for the more expensive stuff (4 digit price tags and up). Cigars, brewing kits, etc.
The "regular" groceries and cookware section are the entrance.
A health foods area, roughly large gas station in size.
Then the main cool factor (and biggest section) is international foods. There's no real good way to describe it with words.
