Time to knock this 4.5 star overall rating down to earth. This place is not very good. I do not have any fond memories of eating this for lunch when I lived somewhere else, like the other reviewers do. Perhaps the nostalgia is clouding judgment.
It reminds me of Which-Wich in the taste and type of sandwich, but with far less options and more expensive for a smaller sandwich. The bread is ok, but not good. Another review mentioned there isn't really anything interesting about the sandwiches and I completely agree. Their signature seems to be milkshakes, but that's sort of a weird thing to have in the middle of a workday during a quick lunch.
It is new, and it is packed, but the service was very good. The long line didn't take as long as I would have thought, but it still took awhile.
Overall, this place is ok but not good. It's generic fast food sandwiches that are equal to the plethora of other fast food sandwich options. I would not seek it out amongst others and would much rather have a good Italian deli Uptown to service my sandwich needs.
