LONG ISLAND, NEW YORK:
If you find yourself on Long Island on a Friday night, looking for mediocre - slightly close to good house music, and what I mean by that is: bearable house music where you don't feel like smashing your head onto your table kind of music visit Chi Restaurant/Bar/Lounge located at 103 Post Ave, Westbury, NY 11590
WARNING: Expect not so good service, but if you get great service: MARVELOUS! (I speak for inside the restaurant, as I did not get to go outside to the patio on that date because it was rented out for a private party).
The only reason why the mediocre service was excusable enough to recommend this place is because it's probably the closest thing to a non-mainstream house music playing spot on Long Island.
Of course, the attractive patio with a bar, seating area, and not so bad sound system also help these matters, especially if you're not entirely interested in a dining night out.
