The food is tasty and fairly-priced, especially when you consider all that you get with a meal and the size of the stacked sandwiches. I had the Jewbano (their take on a Cubano) and it was tangy and delicious. The homemade pickles were a nice touch and I enjoyed the Matzo Ball Soup.
The service was great: friendly and efficient without hovering.
Added bonus: While Nu doesn't serve alcohol, you can bring beer or wine without being charged a corking fee. Our server even brought us wine glasses.
