Instead of restauration, we have now a restaurant.
And maybe it will not be the only one...
It's much more fun to go in the Misty Mug Tavern and order a delicious steak and a grape juice instead of casting a spell to get full.
To help with the service. How about a NPC Waiter somehwere in the back so if you do need food, you can order it from the NPC? May not have a semi-human touch to it, but you'll be able to get food.
