If you're looking for ways to express the concept of "no frills" without using those exact words, there are several alternatives to choose from. Phrases like "basic," "simple," or "unadorned" can all convey the idea of something without any unnecessary embellishments or added features. Other options include "no-nonsense," "utilitarian," or "bare bones." For a more playful spin, you could also say something is "stripped-down," "spartan," or "minimalist." Whatever term you choose, the key is to emphasize the lack of extra bells and whistles, making it clear that the thing being described is all about function over form.
