Does anyone else do this for the rest of the week if you've been out for a meal?

Never used to, but restaurant prices were not as extortionate as they seem to be nowadays.
Went out for a nice lunch today, spent around 70, which is quite a lot for us, but we wanted an end of holidays last meal.
Now I will probably cut right back for the week on food spending.
For example, simple pasta dishes, omlettes, beans on toast and jacket potatoes for the week.
Does anyone else do this?

For 2 people?
Hardly.. especially if you have starter, desert and a drink.
