Armstrong's, I just can't stay away.
Every time I'm near by my parents house, I suggest that we stop at Armstrong's.
I'm not sure if there's anything in particular that Armstrong's is doing out of the ordinary, but their food makes me feel like I'm a part of their big family. The food is primarily Italian and has a lot of heart. The portions you get for any dish are always more than enough to take home for leftovers.
During my last visit I ordered the chicken salad and my boyfriend got a calzone. I chose ranch as my dressing- I don't know what they put in it but it is the best ranch I've had hands down. My salad came with some garlic toast, was full of veggies and chicken, and was also "Pittsburgh-ized" and included fries. The calzone was literally gigantic and had as big of a flavor. It was saucy, cheesy, and crispy.
This place is easy to find a seat in during the day or weekday night, but if you're looking for a spot on a weekend evening make sure you get there early as there's usually a pretty decent wait.
