A Grahamwich staple is their popcorn. Once heated, the popcorn is tossed with parmesan cheese, herbs and truffle oil.

After eating popcorn and sandwiches, the group moved on to Go Roma where they dined on an assortment of pizza, pasta and salad.

Always a food tour favorite: Portillo's hot dogs. Members of the food tour completed their travels at the eatery where they sampled a variety of hot dogs, ending the meal with chocolate cake.
