It's too hot to cook tonight.

Go to the Bourse (Fifth Street between Market and Chestnut Streets), where Gravy Night will benefit the Cystic Fibrosis Foundation.

You get macaroni and meatballs, wine tastings from local vino makers Vincent Novello and John Tenaglia, and fun with author Lorraine Ranalli from 6 to 8 p.m. It's $35 online but $40 at the door.

Info is here.
