Compared to the Grum's in Coventry, this place doesn't come close. The inside feels like you are walking into what I would imagine a Russian bakery would feel like during the cold war. Sparse and lacking in imagination. The people working there reflect the decor to you as well- they are about the most unhappy people I think I have ever met.
That being said, the subs are still pretty good, but I do think that the Grum's in Coventry taste better. Not sure why- probably the same ingredients, maybe it is just how they are put together or something? This place is great if you are in the area, need a quick sandwich (because there is never a line here) and need to keep moving.
Keep in mind that their large sub is about 2 feet long. I have put a couple down myself, but don't need to eat the rest of the day. The Turkey Ridge is one of the best subs, but my buddy always gets the hot subs which he swears by.
