Here’s a few #s for you, just to give you a head start. All #s are listed with Israeli area code, so if you’re calling from America, drop the 0.
There is one hall in Modiyin Ilit. I’m not sure that this is the one my friend’s daughter got married in, but it’s the only one I founded listed in this part of EY. It’s called Nof Ilit. Phone # 08-979-7992.
Ora, Moshav Ora’s hall’s # is 6419962.
There are tons of #s listed in the Madrich Chareidi. Just know that you will probably have to bring your own caterer for these halls. Most catering is Eda Hachareidit kashrus. You have to decide if this is what you want, depending on which people you will have coming that you want to be able to eat there. Oif Simchas is supposed to be one of the cheaper caterers from what I’ve been told.
Mazel Tov and hatzlacha with the preparations.
