Best use of four $25 food credits.

Each trip, I do a guest survey which rewards me with four $25 food comps that you can use at any Ceasars eatery.
I like KGB, especially their Captain Crunch shakes and their sliders, and usually meetup with one of my Vegas friends for a lunch buffet at The Rio, where his local id gets us a 2-1 so the $25 covers both of us.
Last trip I used one at the Hash House inside the Linq and came away pretty unimpressed. Outside of their giant pretzel, the food seemed mediocre and the portions were not particularly large.
Im looking for suggestions to spend the remaining one or two.

Sadly, KGB is closed. We like the mac n cheese burger at Guy Fieri's, but it is pricey. Gordon Ramsey BurGRr is very good, but everything is ala carte and the burger portions are "normal" sized, not XL. Burger Brasserie at Paris is decent as well.

There is a new food court at Caesar's, but we haven't tried it yet.

$25 doesn't go too far in Vegas. I would NOT recommend Buca Cafe or Tequila Taqueria at Bally's.

The Yardhouse at the Linq has a good happy hour M-F from 3 pm - 6 pm. There are both drink and food spcials.

Where do you get these?

Where do you get this guest survey?

Yes, I am curious about the survey as well!
TT at Ballys is now a new MX place...
