This is the closest grocery store to my house but I actually treat this store more like a bodega and just pick up the milk and bread or a coffee and some prepared food on my way home. Why? Because I typically don't carry a shopping cart full of dough around with me to pay for my groceries!
Yes, the store is fantastic for picking up some specialty items. You need a specific type of balsamic vinegar? Yup they probably have it. Iberico cheese? Yup, got that too. You will definitely find high end products here that you won't find at other retailers, so from that perspective it is terrific. However, I shop a mile down the road to do my full grocery shopping because I figure I don't need a grocery store to validate my net worth.
