Here's the thing: I and my family love Rosenfeld's Bagels (Newton Center). I'm hosting a brunch on Sunday, which falls within Passover and is also Easter. This obviates the possibility of finding Rosenfeld's open (they're closed until next wedensday), certainly rules out Kupel's, and basically any authentic bagel shop within driving distance is likely to be in the same boat. Even Bruegger's might be closed on Easter.
Help me out, 'hounds. Where am I going to find decent bagels on Sunday? A change of the event date is not an option.
AlanH (tm) - you've got particular incentive in coming up with good options.
