Does anyone have any info about this firm, particularly their NYC office?

I got a callback to their Chicago office. They used to be Sonnenschein if you didn't know. I had to look them up twice on Vault, but look up Sonnenschein instead and you'll find a bunch. They don't seem to have changed much since the Denton merger about a year and ago I believe it was. I'm interested in lit and I was told by the screener the Chicago office, at least, does a ton of class action defense. Don't know about NY though.
