Of the top 3 pizza places in Athens*
If you like Little Italy, you'll like Peppino's, and maybe even a little more, since their menu encompasses all of Little Italy's and then some. Most notably are their hot and cold sandwiches, including but not limited to chicken parm, eggplant parm, and veal parm. Biggest sandwiches in town. I'm also a fan of their salad bar.
The place has more of a family restaurant feel, naturally, than its downtown counterpart, and as a result you may find friendlier service, since the staff doesn't have to deal with drunken 2am crowds.
I've been going here for around 10 years and never had a single issue or complaint. This is our post-football-game tradition and its always packed at that time.
*I put Little Italy and Transmet in the top 3 too. Whiplash was fantastic, but closed, sadly.
