Hot food sounds like a great idea.. though perhaps I can suggest that the "Respawn/Tank Cafe" is moved from the entrance to a larger area? I'm thinking perhaps near/behind the express check in that was at V17 (so you could just move it forward after say midday) or in the alcove as there appeared to be a large unused area at the top.
From last lan it seemed you were a little cramped and adding a pie warmer/hot dog assembly area is going to make you feel like you are in a shoebox
Coffee sounds like a good idea, but again maybe you can hire a coffee urn? The one i used to have held quite a few litres of coffee which ment refilling was a once every couple of hours.. definately ++ on the busy-ness as it means your not standing there for a half hour every hour refilling it.
On a side note: Have you thought of providing healthier options? I know 80% of people don't want to healthy foods but perhaps you could look into providing pack sandwiches/fruit salad? I'm fairly sure you could pick up the triangle sandwich packs fairly cheap and then its just a matter of making them the night before/during the day and popping them into the fridge. And Fruit salad is easy as!
And if you have the space, maybe respawn can provide a microwave next time? I don't know if one was provided at V17 but i know it would be handy as, not only for those that would like to bring their own food, but also for those who wanna make popcorn for movie watching
