McFadden's Rockville Centre
210 Merrick Rd. Rockville Centre, NY 516-442-2600
McFadden's, part of a national chain, landed on Long Island in November 2009 and draws a big crowd for its drink specials and midsize dance floor. Part of its appeal: Proximity to the Rockville Centre Long Island Rail Road station, and the village's stretch of other pubs and bars. DJs spin several nights a week, and the pub has 18 TVs.
The crowd: Mostly 21- to 30-year-olds
Atmosphere: Loud and lively
