Are you looking for tasty and filling or for the highest bill I can rack up?
If you are looking for tasty and filling Cosmic Rays chicken and Rib platter fills the bill. If you are looking to rack up the highest bill, PepperMarket

but your dessert choices are limited . Sunshine Seasons has some choices that are giant, $$ and not so tasty but others that are very tasty, filling and not going for the most expensive without reguard for what you enjoy eating.
Tangeriene Cafe has the Schwarma Platter which is large as well.
Really, the most bang for your buck will be where you are satisfied after having had your meal regardless of the $$.
My favorites are
Pizza at Pinocchios--Pizza/salad combo with drink and cannoli maybe add a side of figaro fries with a snack credit
We enjoy Tangeriene Cafe so the Schwarma platter is a good fit for us
My kids and DH love the sandwiches at Sunshine Seasons
My kids like the orange chicken in China with the red bean ice cream and a drink
DS loves the ham and cheese croissant and a strawberry tart with botled water in France.
I like the plato combinacion in Mexico
It isn't so much maxing out the $$ value as it is enjoying the choices that you make.
