Jimmy Johns are good, but the subs are much smaller than Jersey Mikes for around the same price. They do have an “unwich” where they wrap the sub in lettuce leaves for those on a low carb diet. If you like Italian subs, get the “Vito”. They do have a good vinaigrette.
There’s a “New York Sub Hub” here that I think is about as good as Jersey Mike’s but 1/3 cheaper.
