The giant panda enclosure has a barbecued intestine, but no other food to eat. Some animals haven’t come out, like river otters and giraffes and so on. We just came to see the giant pandas. It’s cold outside, few people.
There isn’t, and there’s nothing open inside during winter. It’s recommended to bring your own water and food. It’s even more advised not to go to a zoo in winter, as many animals are inactive anyway.
The zoo cannot have self-service restaurants, take some food when you go and bring it to your child.
“None, let’s bring some food ourselves. There are small grocery stores.”

(Note: “自备些食物吧” can be translated to “let’s bring some food ourselves”, which implies that you should prepare your own food instead of relying on others or buying from a store.)
Not too clear, probably none, but there are small stalls selling things that might be a bit more expensive than outside ones, best to bring some snacks to eat.
“There’s no need for this mom to suggest bringing some bread or something when you go in. This zoo is very big, and things inside are also quite expensive and not suitable for kids to eat.”
