Fellow Jersey ex-pat here - most of the in town options are terrible. The best pizza I've found is Pepe's, although I have not ordered since they moved to Shrewsbury St. We usually end up getting Antonio's since they do a much better job with delivery. Volturno (go Monday or Tuesday for BOGO) has really good pizza too.

Best bagels I've found is Cafe Fresh in Sterling. It's a haul so we buy a couple dozen and freeze them. Most MA bagels are round bread with a hole.
