To the many of you who recommend Casa Vasca, add my vote!
Went to Newark in the downpours last night to meet friends en route back to Kansas. Abandoned plans to venture out of Newark and went to Casa Vasca for a wonderful meal with good service. As others point out, it can be noisy, which it was even at 9 on a Wednesday night with a retirement party winding down; but it was a friendly rather than rowdy kind of noise. This place doesn't have the barny feel of some of the other well-known places in the Ironbound. I'll be going back.
