I had been in the store several times before I discovered the downstairs section. A very large selection of French novels, short stories, non-fiction, etc. Some newspapers, magazines, and records. They also have a reasonably large selection of dictionaries and instruction books for other languages.
Prices tend to be high, though there are occasional sales in their basement.
Staff is usually fluent in French. 6th Ave at 48th in the basement of the McGraw-Hill building. Their finance section is also good. It also has its own publishing company so they also have the latest copies of their own line of mysteries. Book-signings by authors.
