First off, don't come here expecting high gastronomy. This is a workers lunch and it's pretty clear. If you accept this and that this is not a healthy lunch, you can be satisfied with the lunch at wilensky's.
I walked there from my office and took it to go. I had 2 special wilensky's sandwich, one with Swiss cheese and one with no cheese. If you are hesitating between the two, my answer is simple: go with the one with cheese. The standard one is a good comfort food but the one with cheese is so much better. The cheese melts completely and the taste of Swiss goes really well with the salami if the sandwich.
Also try their soft drink. They are homemade and tastes really good. One warning though, don't expect it to taste like your commercial version of the drinks like Coca-Cola or Pepsi.the taste is different but it's really good
