What's "no-frills" mean here?

"No-frills" is an adjective. Here it means not fancy, elaborate, or extra comfortable. It's only the essentials. They're referring to a wealthy life where having more "frills" is common, but here, Rachel would like "no-frills." Ex: I want a no-frills bike without a basket and fancy ribbons. It has to be a plain, boring color. Ex: It's a no-frill flight. They don't supply drinks or food.
