There are some places you go and you can just be comfortable going there. Subway is like that - it doesn't matter what town you are in you will always get a top notch sub with great toppings every time!
My personal favorite is the BMT (no, it's not Jared approved LOL) which stands for Biggest, Meatiest, Tastiest! I get it piled high with spinach, lettuce, and black olives but there is a huge array of toppings you can choose from.
The bread is always fresh made and soft - and you get a great selection there too! Many different types to choose from.
