There are a couple of ways that you can go about tracking food while eating out.
The first way is if the restaurant has available nutrition information. If the information is available, you can use the search feature in your food logging database and search up the restaurant and specific food item.
The second way is if the nutrition information isn’t available. You can then use the AI food scanner feature to get a better estimation of the calories and macros in your dish.
