I haven't been to a Celebration Station but I have been to a place just like that while visiting family a few times as a teen (and even early in my early 20s I think)I do anytime I want to recreate that AUTHENTIC 1980s bowling alley snack bar experience. (The snack bars at my local bowling alleys served Tombstone exclusively)
Home Run Inn pizza is something I pick up from time to time. Gotta take a trip down the I80 corridor to actually find one to eat at in the wild. But I think Home Run Inn frozen has a unique taste to the crust--not something you'll get if you're looking for CEC or Showbiz. My city once had a Celebration Station--just like CEC and Showbiz. Then the same slot turned into a CEC and has been ever since.
If you want CEC like pizza... maybe Casey's or Noble Roman's?
Also: You can still find Celebration Station: http://www.celebrationstation.com/
Same basic idea though of a place with go karts, arcade games, laser tag, a bowling alley and a place to eat.
I don't think I ever ate any pizza there though, but if I ever make it back there (and if it's even still a thing) I'll be sure to check out the pizza.
