While you may have heard the saying "Good things come in small packages", this surely doesn't apply to sub sandwiches. When given the option of a 6 inch or a footlong, paying the extra few dollars for the footlong is a decision you won't likely regret.
Even if I have no intention of eating 12 inchs of Sub goodness, I always order a footlong. In my experience, any uneaten sub inches can be frozen for up to 3 years for consumption at a later date. View more of Mitch's tips.
