I agree. There's not too many clubs anymore in East Orange. Years ago (4+ ?) the city used to have several clubs. But the city used various means to discourage them and so you'll find a lot more in Newark and Elizabeth.
There's 'The Lodge' on Central Ave. in Newark, 'Atmosphere' on Wainwright and Nye in Newark, 'Loft 47' on Edison Pl. in downtown Newark, clubs 'Sho' and 'Dolces' in Elizabeth and 'Four Sixty Six' on Prospect Ave. in West Orange (right off of Rt. 280).
