There are also a few dining discounts for DVC without the TIW, mostly for lunch.
Most of them include everything, drinks too, but I don't drink alcohol so I cannot be 100% sure for it.
There are a few exceptions, though. Yak and Yet at AK for example applies the 10% discount only on the main (but nothing can stop me from taking the fried wanton anyway ), however it is written on the website if that is the case.
