Are you looking for a specific type of food? I had my rehearsal dinner at Cielo in Fairfield NJ and it was 35pp + alcohol (we had 50 people). They did a good job, food was really good and they were super close to the hotel we used for out of town guests.
I would also recommend Amore's in Wayne NJ, not 100% sure on their prices. They are either comparable or slightly more expensive - food is really good!
We're having ours at Michaelangelo's in North Arlington. We're keeping it simple - brick oven pizzas (theirs are AWESOME) and salad, with a few apps, but their regular menu is great too. They're BYOB, which will help cut down on costs.
140 invited -- 118 are ready to party! -- 27 can't make it
We are using Porcini in Totowa, amazing food, good prices and byob...fyi about Amore, they recently changed from a byob to a full bar, we looked there too but wanted byob
