The Good: I always take my out of town guests to Fat Heads. It's one of my Pittsburgh "landmarks". I love the ridiculously over-sized sandwiches, and I'm a sucker for house-made chips and fries. Plus, who can resist that beer list? If you've got a large group, order apps. Pierogies! Pretzels! More Chips!
The Not-so-Good: I'm always disappointed with anything that includes Parmesan. They always use WAY too much of it. It makes me sick.
