I am opening a bistro and i am currently working on my kitchen design and layout. I have decided on buying a deep fryer with a double tank. But i am not sure if a counter top variety or a stand up would be better for what we are doing. I am considering a counter top electric for the extra space and from what i have read electric seems more energy efficient. Can anyone list the operating differences between a standup and a counter top fryer? Also does an oil filtration system work with a counter top model?
