One more menu from 1934. Some barbeque items on the menu. My Father had a large hickory wood fired smoke barbeque rotisserie. Driven with an electric motor and chains on sprockets to turn the spits.
It could cook up to 50 chickens at one time. This was quite the novelty back when he had it built for the restaurant. It is quite a common machine now, and often seen even in deli counters at grocery stores ,where they cook up chickens and spare ribs for ready cooked take home food.
