Don't come here in the summer. Don't do it. Listen to me: DON'T. The combined heat of a cramped and crowded restaurant without air plus meat sweats is not something you want to experience.
Plus, be prepared to wait but be adequately hungry enough for the massive portions.
Henry Wahner's is quite an experience. It's like sitting at a friend's grandma's house. Not your grandma, no, it's not quite cozy enough. There's distance to how comfortable you'll feel here, starting with the mess that is parking atop the hill.
My boyfriend ordered a 30 dollar steak and mozzarella sticks to start. Hilariously, we were told the mozzarella sticks were served with marinara, but instead we received shrimp cocktail sauce. All nine in our party asked what the deal with that was and we received the answer that the sauce WAS marinara. Uh. Ok.
Anyway, while my boyfriend took some of his steak home, our friend tested the limits of his stomach and ate his entire steak. The next morning he notified us that he could barely move and had gained nine pounds from the previous day's weigh in.
We still had some dessert and the apple strudel a la mode was most definitely delicious.
Plan your visit strategically and you'll have a much easier and more enjoyable time here.
