How to log a restaurant lunch menu

Many restaurants in Central Europe offer a cheaper weekday lunch menu – usually a soup and a main course. For a food diary that is good news: the restaurant writes most of the information on the board for you.

In short

  • Log the soup and the main course as two separate entries.
  • Add a photo of the menu to each plate photo – name, weight and side dish.
  • A weight on the menu usually refers to the meat, not the whole plate.
  • Restaurant food tends to contain more fat, so round up rather than down.

Why a written menu helps

Restaurant food is harder to log than home cooking – you cannot see how much oil went into the pan or what is hiding under the sauce. A daily lunch menu has one big advantage over a normal à-la-carte dish: a written description. The board or card often lists the exact dish, the side, the meat portion weight, the soup volume and allergen codes.

The plate photo shows what the food looks like. The menu photo tells you what it is. Together they carry far more information than either one alone.

The method: two photos per dish

1. The soup

Photograph the bowl from above. As a detail photo, add a shot of the menu line with the soup – for example "Chicken broth with noodles 0.33 l". You do not have to retype the name or the volume.

2. The main course as a separate entry

Do the same for the main course: plate photo plus a photo of its line on the menu. Separate entries are easier to correct one by one and can be saved individually if you order the same dish again.

3. A short note when something differs

Half a portion of rice, sauce on the side, or you did not finish? Add a note. A few words like "half the rice, no tartar sauce" change the result more than better lighting.

4. Check the proposal before saving

Go through the suggested ingredients and the weight of the whole portion. If something does not match your plate, correct it – the proposal is a helper, your entry is what counts.

How to read weights on the menu

  • "150 g" next to a main course usually refers to the meat, not the whole plate. Side, sauce and garnish come on top. If in doubt, ask the staff.
  • For meat, it is often the weight before cooking. Cooked meat loses water and weighs less on the plate, but the calories stay.
  • Soup volume (e.g. 0.25 l or 0.33 l) is useful – enter it instead of guessing "one bowl".
  • Allergen codes say nothing about calories, but they reveal hidden ingredients such as milk or egg in a sauce or coating.

Common traps

  • Fat: fried dishes, cream sauces and butter on the side add the most. One tablespoon of oil is about 119 kcal.
  • Sides: restaurant portions of fries, rice or dumplings are often generous. If there is more than you would serve at home, adjust the amount.
  • Drinks and dessert: the lemonade that comes with the menu or a pastry at the till are easy to forget. Log them straight away.
  • Regular dishes: if you often eat at the same place, save your favourite dish and next time just adjust the portion.

Even with the best method, a restaurant estimate will not be perfect. What matters is consistency – the trend over several weeks shows whether your routine works.

Frequently asked questions

Should I log soup and main course together or separately?

Separately. Each dish is easier to correct on its own, and you can save favourite dishes and reuse them.

What does the weight on a lunch menu mean?

For a main course it usually refers to the meat, often before cooking, not the whole plate with the side. If unsure, ask the staff.

Why photograph the menu if I already have a photo of the food?

The menu contains the name, side dish, soup volume or meat weight – information you cannot read from a plate photo. Together they give a better basis for the estimate.
