Dinner near movie theater in Washington Township (Bergen)?
Not sure of "nothing too $$" as that can be a relative term -- but there's a few I would recommend. First, look at Bacari Grill, right on Ridgewood and Pascack in Washington Township. They've undergone some changes lately -- all positive. Also, check out Granita Grill (BYO) on Broadway in Westwood. It's right there. PJ Finnegan's -- also in Westwood, on Fairview -- is right there as well. It's a small, casual Irish pub with a separate dining room from the bar -- burgers, pub grub, sandwiches, other dishes, etc. It's good food for a nice little pub.
Good luck and enjoy.
