The Gateway Grille in Monroeville is evidently a very popular place with the locals. I had to wait to get seated at 8 pm. There is no hostess stand or obvious place for you the stand to be seated. I had to ask where to go.
If you don't like noisy, sports bars this isn't the place for you. There is a dull roar in here from all the people speaking. On the walls are 17 big, flat screen TVs, all tuned, naturally, to Pittsburgh sports games.
The menu has a good variety with reasonable prices. The food was delivered promptly. I got a calzone with sausage and mushrooms. It was very tasty.
This place also as a bar on one side of the restaurant. The is also an adjoining package store where you can get 6-packs of beer. Reminds me of places in Philadelphia.
All in all, it's a good place. It just loses points for the extreme loudness.
