Among a certain breed of sweettooths, cheesecake can easily provoke the same regional fights that pizza inspires. For our money, the Second City has the best mail-order variety available, thanks to the venerable Eli's (a company that also owns the old-school hangout, Eli's the Place for Steaks). The Chicago-style treat features a firm exterior, softening to a creamy texture on the inside. The combination never fails. Order here.
