Important: please read
Low-carb is not the same as keto, gluten-free, or low-calorie. A low-carb item can still be high in fat, sodium, or calories, and carbs vary by location, portion, and preparation. Confirm against the restaurant's official nutrition/allergen guide before ordering.
Top Picks

How This Guide Was Built
We list every menu item in our database that has a carb value of 20g or fewer from official restaurant nutrition data. Carb counts reflect the single item as listed, before optional toppings; items with no carb data are excluded. This is a menu-information guide: a 20g per-item ceiling is a useful filter, not a medical prescription.
Menu Labeling & Nutrition Information
2,000 calories a day is used for general nutrition advice, but calorie needs vary. Full nutrition information, including saturated fat, trans fat, cholesterol, sodium, sugars, and fiber, is available upon request from the restaurant and in the official nutrition guide. Calorie counts shown are approximate and based on official restaurant nutrition data; values may vary by location, preparation, and portion size.
