I ordered shrimp Alfredo , they didn't have it menu, but they did it for 24$ wich is pretty expensive . On the check they put 17 $ for pasta and 7 $ for shrimps. So i got this pasta with shrimps and was very disappointed.The Alfredo souce wasn't even tasting like it should. Got scamed with 17$ pasta.
