I'm planning a casual dinner for fifteen or so and thought that shabu-shabu would be fun. Would people mind weighing in on the pros and cons of Kaze and ShabuZen? I've had shabu-shabu but have never been to either restaurant. Will the size of the group make a difference? I've seen on other sites that shabuzen doesn't take reservations and only seats tables when they are complete. Is this true? Also, does either place serve alcohol (beer? sake?) Anf most importantly, which has the better broth and freshest ingredients? Thanks in advance for your input.
