Perle is my fav. It sticks out here in Pittsburgh for two reasons. I absolutely love the service here. The staff are friendly and quick to recommend food to eat and help you navigate their champagne cocktail menu. My favorite is their sparkling sangria that is in the top five when it comes to the best sangria. I've tried lots of sangria but the sparkling aspect is freaking genius. I also love the music and the decor. As soon as you walk up the stairs of Perle it's almost unexpected for it to be so nice. The balcony view is also a great view of the square Perle sits in. I always have a great time when I check this place out. Their drinks are a little on the pricey side but it's worth every penny. Their food comes from their sister restaurant Nola and Nola is great food.
