North Las Vegas, NV Good for Group

Hi all HO’s. Hoping you might be able to help me out. Hubby’s paintaball team has a tournament in North Las Vegas the end of May. We are looking for an Italian/Pizza restaurant for Friday night and a Mexican restaurant for Saturday night that takes reservations and can accomadate a group of 18 (12 adults, 6 kids; 1.5yrs-9yrs), with on site parking. A private room would be nice but not necessary. Good solid middle of the road food is fine-his team doesn’t have very adventurous palates. We have access to cars but would like to stay in North Las Vegas area. TIA.
