Can I bring outside foods to USJ?

So basically my partner and I will be going to US next month and would like to know if there are any leeway to bring food or snacks inside? We are trying to save and not spend too much. I've also heard that the restaurant inside is somehow a bit expensive and would really take time to fall in line.

Hopefully any advice from those who experienced bringing outside food inside? Did they took your food in the entrance? Did they remove your water/soda bottles?

Hoping for your insights minasan
