No, Fatboys Phillys does not appear to be halal certified. We couldn't find any claims from the restaurant that they are halal, and their menu includes items like bacon and pepperoni, which are typically not halal.

They don't seem to serve alcohol, but they do serve pork. Their menu on several delivery platforms lists items with bacon, pepperoni, and sausage. We haven't found any information about how they prevent cross-contamination between these items and other foods.

We found no information to suggest that the meat is hand-slaughtered (zabihah). Given that the restaurant serves pork products and makes no halal claims, it is very unlikely that they use hand-slaughtered meat.

The restaurant itself does not have a prayer room. You would need to find a mosque or public prayer facility in the Hoppers Crossing area.

While the restaurant can likely accommodate large groups, it's important for Muslim families to be aware that it is a mixed kitchen serving non-halal products. We would strongly advise you to speak with the restaurant directly about your dietary needs before booking a large gathering.
