I'm not at all familiar with "new Jewish cuisine", so I don't have much to compare NU to, but I enjoyed my experience.
My friend and I sat outside and the server was very attentive. I ordered the Upstreet Dip, which seemed to be pretty popular. It was heavy, but not too greasy. The coleslaw was pretty standard. The presentation was nice- the sides are in takeout containers and the water is poured into Mason jars.
I've heard that their brunch is good- I'll have to go back to check that out!
