addicted to food

I feel like I have a real problem. I have a hard time resisting the urge to Buy food (like uber or going out every weekend) I want to be able to save more especially since DH works and I don't. one income family. We have $400 per month towards food. It's just the 2 of us plus 2 cats and one dog. is $400 reasonable or should we lower it to save more money? we have it at $400 per month so we can buy healthy meals. any suggestions for how we can change this and save better?
