i only really like the pumpernickel bagel for its "fluffy-chewy" texture. chocolate-chip is ok, but it's definitely the chocolate. try it with cream cheese for something that resembles cheesecake for breakfast.
their bagels are not very typically bagel-like; neither montreal nor ny styles. similarly, the "topped bagels" are completely un-bagely, but still uniquely good and filling.
i've tried the others, and will not ever again.
since this GBC does not have seating (it's inside the subway station), grab n' go is the only option. the beverages do not warrant attention.
