Most expensive sandwich in Harvard Square

I was in Cardullo's for lunch yesterday -- I heard that they have good sandwiches. Their sandwiches are pricier than Darwin's by a couple of dollars (ranges $9-12), in case you were thinking about going there to try their sandwiches. My Italian sub was intensely flavorful -- hot peppers, balsamic vinegar, salty meats and sweet tomatoes.

The most extravagant sandwich is the caviar sandwich. It sells for $130. It also made me wonder what else I can get in Harvard Square that is tasty for $130.
