There is an old post about how great this is so I think I need a counter-post.
I ate there before 1990 &even then it wasn't great. Was crowded (inside& outside), and building looks ugly (inside& outside).
The 2 negative posts described this correctly, I think. The "bread" they are talking about, is not great, like Subway. Someone said machine made.
To answer that person's post, there is a lot better stuff. (both quantity& quality) It would have to be really extraordinary to make it worth the wait& decor.
