Road trip advice

We are going on a little road trip for my birthday in 2 weeks.. He’s a picky eater does not eat much. We are staying at a hotel just for one night. Was hoping for some suggestions of what I should bring with me for him to eat. He’s on whole milk and also toddler formula right now. He drinks the toddler formula at bed time im just trying to finish the formula that’s left. Debating on just taking that with us and not give him whole milk to make it easier. He drinks whole milk in the morning. How do you travel with whole milk? Not sure what to do about food. He likes eggs so if we go out to breakfast I share my eggs with him. Other than that he’s tough to feed for the rest of the day. He likes pouches I plan to pack some of those. But not sure what to do about lunch and dinner. For Dinner we will be going to a steak house. At home he only really likes toast and chicken nuggets.
