I don't spend much time reviewing any type of chain as you should be able to get a similar experience no matter which location you go to.
Its higher quality food than your average grocery store, but I just don't get the niche. Its as expensive as an Earth Fare or Whole Foods without the organics. They really just don't have that large of a selection in general compared to the other 2. The only reason I ever go is if there is some type of sale, I want a sandwich or sushi for lunch, or I just need a nice cut of meat or seafood.
Its just not my kinda place, but you can still get lunch quicker and cheaper than pretty much any restaurant.
