Had an excellent meal there recently. Lovely beef carpaccio, followed by a "Tuscan Grille"--a thick-cut, perfectly cooked steak with oil and rosemary. Really, really fine. I asked the chef why she did not call it Bifstek Fiorentina, which it certainly reminded me of. She said it was a different cut, but if I called in advance she'd fix the Fiorentina.
I have been to Mangia Qui several times over the years, and always found it first-rate. Nice place where everyone seems to have a good time. Professional, friendly staff. Highly recomment it; if I lived in Harrisburg, I'd go there a lot.
