I've been to Fire Side a number of times now and have had a good experience each time. The service and food are always good. The first time I had anything from them was when they donated some wings to a grand opening party at Painting with a Twist in East Liberty. The flavors were unique and delicious (sriracha maple bacon and blackberry bbq).
The menu pulls from lots of local sources, including Dave & Andy's ice cream. Super yummy vanilla ice cream for dessert! It's always cool to get a full-on Pittsburgh vibe when you're at a restaurant.
Due to dietary restrictions (gluten-free), I am limited to certain menu items. The manager, Sean, was very hospitable and brought me a tray of gluten-free sauces to try for my grilled wings. He was knowledgeable and helpful, and really added to my already-good opinion of the restaurant.
Five stars would be if there were more food options for people with dietary restrictions -- keeping separate fryers for allergens, etc., so I could try more foods on the menu to review -- but otherwise, a solid four stars.
