I get hungry within 2 hours of eating a foot long sub too! So, it pains me to spend more than 100 bucks to eat something, and then within 2 hours, spend another 100 bucks to eat a Biryani outside ;-) !
This does not mean to say that the offerings of the menu are not good ;-). To keep it simple, you can just have the Egg with cheese sub. It is the best bet for a quick bite. To make it a little more complicated, you can add your choice of vegetables too. Only Ranch and Red Chilli sauce go good with the egg sub. Chicken Tikka Sub and also the chicken meatball sub are tasty. Mayonese and Southwest sauces are good with these. I do NOT like black olives, and therefore avoid them at all costs!
I never knew I will say this - but their veggie delight salad is truly a delight! If you get a chance, don't miss it!
