I've had dinner at the Oliverio's in Bridgeport a number of times, but never the one in Morgantown.
Down this way there is Muriale's in Fairmont and Minards in Clarksburg also. Muriale's and Oliverio's are pretty close as far as I'm concerned but I give the not to Oliverio's. I don't recall ever having Puglioni's but I can't imagine getting much better than Oliverio's.
I would probably drive to Fairmont and eat at Muriale's if I had to make 1 choice for dinner. I recommended Oliverio's because it is in Morgantown and is probably a quick Uber or cab ride. I would not go to Puglioni's but I know Mog is high on it and others like it so I am only giving my opinion realizing that others disagree.
Muriale's is probably comparable to Rocco's in Kenova if Marine knows that place. Rocco Muriale founded Rocco's and his nephew Rocco Muriale founded Muriales in Fairmont. I think they are pretty close in recipes.
