My dad is on a low-carb, low-cal, low sugar and low/fat free diet due to health reasons. He's coming to visit me next week, and I want to find an ice cream shop in the Bay Area they offer soft-serve yogurt (like carbolite or wow cow brands) that would fit his dietary requirements listed above. As a treat he usually eats his 10/cal per ounce frozen yogurt everyday near his home in NY, so ideally I would like to find a shop around here. We'll mostly be in the Palo Alto, Mountain View areas and SF during his visit.
Thanks for your advice and help!
