Dinner Rec for the NJ Union or Essex County
I know this is a couple weeks late, but Raagini in Mountainside is right near the theater, and is by far the best Indian food in the area. The diner right next to the theater is your average Jersey diner, but it offers a package deal with the theater. Famous Dave's BBQ is right down 22 and pretty good also.
I know both places very well. I am a fan of Raagini. We ended up at the Outback across 22 instead and was very disappointed. My burger was cold my husbands burger was overcooked and came out without his fries. He had to wait another 20 minutes for his fries.
My new find is Toro Loco in South Orange for a night of Mexican food and Margarehitas. It's loud fun place okay with children and loud friends.
