*The Snowman thinks for a moment, before finally speaking* Well, there's always the possibility of a 24 hour diner or convenience store being open, but I'm not sure if any of them would serve vegan food. There might be a few restaurants that offer delivery or takeout, but it's unlikely that they would have vegan options. If you're really desperate, there's always the possibility of finding a 24 hour grocery store and making something yourself.
