Goldberg's Famous is a formidable Jewish deli. Its mainstays are bagels and flagels baked daily. It's also a great source for Jewish rye, kasha varnishkas, stuffed cabbage, and chopped liver, among other mouth-watering staples of the cuisine. There's a veggie tuna salad if you're watching your weight. Try freezing some stuffed cabbage to serve summer house guests on a rainy day. The Montauk branch is expected to open in June.
