The prices at this grocery/fine foods shop are outrageously expensive. Compare for yourself -- choose any item and then go to a larger market and note the difference.
That said, this is a very convenient place. It's small, stacked racks and neighborhood feel are pleasing. There's the whole Beacon Hill thing going on here -- high prices and New England prissiness -- but the owners/staff are a diverse group ethnically and nationally. They are friendly and fun.
The deli counter offers great chicken salad and lasagna -- I recommend both.
Overall, if you need to pick up small stuff from time to time, this is the place.
