Go to the Ironbound if you want good food. Casa D'Paco and Vivo Tapas for Spanish cuisine, Boi Na Brasa and Brasilia for Brazilian BBQ are some of my first recommendations, but there are tons of other restaurants in the neighborhood. The Newark Museum of Art is very underrated. It's a great way to spend the day when the weather is bad. Also, if you're arriving in April, you might just arrive at the perfect time to see the cherry blossoms in Branch Brook Park, which has the largest collection of cherry blossom trees in the US. There's also a Japanese cultural festival and music on April 16.
