Ok kiddo, so you know how sometimes grown-ups go to a place called a pub? It's like a special place where they can hang out with their friends and have a drink. Well, when people are hanging out at the pub, they usually get a little hungry, right?
That's where pub grub comes in! Pub grub is just a fancy way of saying "food that you can get at a pub." Think of it like snacks or little meals that you can enjoy while sitting with your friends and having a drink.
Now, what kind of food is pub grub? Well, that can vary depending on the pub you're at. Some pubs might have things like chicken wings, chips (or "fries" as some people call them), or little sandwiches called sliders. Other pubs might have bigger meals like burgers or fish and chips.
The important thing to remember is that pub grub is just meant to be simple, satisfying food that you can enjoy while hanging out with your friends at the pub. So, if you ever find yourself at a pub as a grown-up, make sure to try some pub grub and see what you like!
