Google screen grab of the old Kentucky Fried Chicken building
The only place in town serving pizza is Brunos on south 1st Street. I am sure this will affect their business, at least somewhat, who knows how much. No real traffic on the south 1st street location, mostly locals.
The Dominos will grab most of its business from the I-25 traffic if they have a "dine in" option. The ones I have seen, and they are few, where you order your pizza and there are there tables and chairs where you seat yourself sort of like the Subways.
The food business is one tough business, but it is the one that a lot of folks think they can succeed at. Just look at the ones that come and go in Raton. They open up the doors and wait for customers who never come. There are way more people who think they can make a living at the restaurant business than there are customers.
