chicken teriyaki sub

I went to Subway yesterday and had a chicken teriyaki sub. I've had them a million times before, so I know they are very delicious. That is the only thing I eat at Subway, besides the spicy italian. I wonder how many other people order this same sub when they go there. Do you like the teriyaki? Do you eat it when you go there? Do you think it's their #1 selling sub, or do you think they sell more of something else?
