Where's the location Jericho Jewish Center?
I'm assuming you're talking about a place on Long Island, NY?
Here's a link to the info from Yellow.com, which is a great way to find locations. (Of course, that's assuming you know the city and state of the place you're looking for.) It has the address and phone number, plus if you click the "Maps" link at the top of the page, you should be able to get a map & driving directions.
If you're looking for some other Jericho Jewish Center - sorry, can't help you.
One final thing - once you get there, hope you will come back and tell us about the food. (Since talking about food, rather than giving directions to places, is this message board's reason to exist!)
