Inventive versions of that childhood classic, macaroni and cheese, have been on the Long Island dining scene for a while. Yet, diners still can't wait to get a taste of the newest variations.

Here are four new takes on an old favorite:

DIRTYBURGER, 12 Manetto Hill Rd., Plainview, 516-595-7399

Chef Ian Russo's "dirty" blend of spices -- a list of ingredients headed by cayenne pepper -- plays into almost every dish on the menu of his burger-centric restaurant. It works especially well in his al dente mac and cheese, a successful side dish. $4

CHOW DOWN DINER, 4011 Hempstead Tpke., Bethpage, 516-597-5310

Chef Steven Del Lima presents a well-edited repertoire of cleverly tweaked American classics at diner prices at the sleek spot with a contemporary-retro vibe.
