Discover's Q3-2018 is on restaurant. I still have the first year card that has the cash match. But I'm not sure if I can max out the spending for the month. I can request some AU cards for family to max it out. But I do not want to have any history on the credit report of new account.

Any GCs that I can buy that can be coded as restaurant at Discover? I have been trying to avoid this since it is not very good to let GC guide your food spending.
