I'm going to get food from a different restaurant
Why would you go to a different restaurant?
The food at the old one doesn't taste good anymore.
It's okay to change restaurants when they don't satisfy your needs. You should try new places so you can get what you want.
Yes, that was my plan. I want to eat better food.
That sounds reasonable. You deserve to be happy with the food you choose to eat and where you get it from.
