endless amount of protein
This restaurant would have very limited options.
However, it would be tasty and extremely healthy.
One of the key benefits would be that the restaurant would weigh out everything for the customer. Then, they would write out the exact number of calories and macronutrients on the product for easy tracking.
It would be similar to Chipotle. Chicken, rice, beef, and fish with healthy carbs and limited fats.
