Mentions gastronomiques
This challenge requires us to recover the price of the meal that Margot Paquet ate. This was a bit tricky because there was an American lady that is named also Margot Paquet and that posted a picture of her meal that she ate for her wedding anniversary.
After a lot of tries, I found another account on Instagram this time. It didn’t look really legitimate, it may be the good one this time:
As stated on one of the images, she likes to eat Boeuf Bourguignon at the restaurant if it cost less than 15€:
Her account was tagged by the Futurionix Instagram account. Looking at the images posted by this account, we can see that they ate in Paris near The Louvre museum:
And they say that they are going to set their HQ near this location. Looking for restaurant near this location that are not expensive, we find the La Frégate. We can find pictures of the menu on google maps. And… a Boeuf Bourguignon at 13.5€!!! (We may have wasted time on the website that isn’t up to date):
But the flag 404CTF{la_fregate_13.5} didn’t work. She may have eaten something with the Boeuf Bourguignon. Heading back to the Instagram account, we see that she ate a Tarte Tatin the day before the post of the picture:
And the Boeuf Bourguignon picture was posted the 26th of April, one day after the Tarte Tatin post. So looking at the price of the Tarte Tatin we find two prices. One at 9€ and the other one at 10.5€:
The final flag was (13.5+10.5=24): 404CTF{la_fregate_24.0}
