The Rusty Nail is a neighborhood diner-style restaurant that serves Pittsburgh-centric comfort foods. Meatloaf, pasta, and hot roast beef all grace the menu.
I came here with my dad who ordered a hot roast beef, and I ordered a bowl of spaghetti and meatballs. Both meals were right around $10 and delicious. The portions were huge, and the waitstaff was very friendly.
I'm guessing it was the owner, but a nice guy came around asking everyone how their food was and making small talk. Nice touch.
