Tried to order online through grubhub and couldn't add pizza by the slice . called and asked for assistance and was told 'i don't know the app is run by another company' i was told to just call to add the slices to the order. Grubhub had a issue so I called directly from Google. After taking my information i was put on hold, the first thing I requested was two plain slices and was told they only had one. I said ok I'll take a pepperoni and a plain. And I was then told oh no there's only one plain slice. I said so your telling me i can only get one slice of pizza right now? She said yes, since it's so close to closing. They don't close for another 3 HOURS! Smh. Pretty sure it's because I gave an address in Paterson. Definitely will not return. A pizza spot with one slice available 3 hours before closing. CLASS ACT.
