I went to No. 7 Sub not long after it opened, about a month ago, and gave my take on it. Eater has a roundup of the still "early word" on the sandwich shop. It seems many have encountered long waits. I tried to go one day around 1:30 p.m. and the line was out the door and I turned around and left. But on the day I actually made it in, around noon, there was maybe one other customer and the wait for my sandwich wasn't long at all.
