This is one of the tastiest spots to visit in the South Hills. You'll find Arancini House within Mt. Lebanon's business district. You just have to keep your eyes peeled for their door and walk down stairs to their lower level location (I believe the elevators in the building can also get you there).
Arancini House is cozy and unassuming, but don't be fooled by their humble set-up. Behind the counter are some of the friendliest staffers I've ever spoken to. They love answering questions and chatting with their customers. And they make fantastic, freshly baked food!
They offer a nice selection of arancini, including a weekly rotation of veggie options. I'm especially fond of the Al Burro (Bechamel cream sauce, prosciutto di cotto, peas). Also available for diners are wedding soup, a couple salads and fried appetizers, sandwiches, and homemade dessert. And of course, their generous helpings of pizza!
I highly recommend stopping in here and exploring the menu at your own pace. At least one arancini is a must, of course. Just be ready to come back for more - in my experience these tasty treats are filling and satisfying!
