I'd bring dinner as well. If it has to be a hot meal, pack it in a thermal container before you leave. It'll stay warm for a couple hours, easily.

I've never been to a Chik-Fil-A, but maybe there is something cheaper that won't cost $25/visit? Could you find something less expensive for part of the meal and supplement with things brought from home? Can you order a pizza delivered to the hockey rink and eat before you leave to go home? Not ideal, but cheaper than $25, I'd think.
