Belt-tightening is all well and good, but man cannot live by five-for-a-dollar Chinatown dumplings alone—especially now, during white-truffle season. Which is why it’s nice to know that the folks at Sapori d’Ischia haven’t raised the price tag on their annual Tuesday-night truffle dinners for the past four years. The deal: Every Tuesday through December 2, three luxurious Alba-truffle-strewn courses for $50. 55-15 37th Ave., nr. 56th St., Woodside; 718-446-1500.
