## Ressources
We were given access to Adam Holmes’ food blog, containing several articles, photos, and reviews of the restaurants he has visited. The website could be accessed via [this URL](https://osint-food-blog-web.chal.irisc.tf/).
The challenge description pointed to one of the reviews Adam shared on his blog. In addition, we were provided with the following image:
## Tools
As this is an OSINT challenge we won't need any tool to solve it. We will only need a web browse, I well be using Google Chrome.
Since this is an OSINT challenge, we didn’t require any specialized tools. A simple web browser sufficed for our needs, I opted to use `Google Chrome`.
## Resolution
### Initial Analysis
Exploring Adam’s blog, we noticed he had shared a few articles one or two days prior, where he mentioned visiting a friend in `Japan`. This clue strongly suggested that the picture was taken somewhere in Japan.
Additionally, in the review, Adam mentioned a deer park. From this detail, we hypothesized that the restaurant in question might be located near a deer park in Japan. The fact that the restaurant served eel, as shown in the picture of the dish, further narrowed down our search criteria.
### Identifying the deer park
Our first step was to investigate well-known deer parks in Japan. The most famous, and the first to appear in our search, was `Nara Park`. Given that Adam is a tourist and `Nara Park` is one of the most popular tourist destinations in Japan, it seemed highly likely that he visited this park.
### Identifying the dish
Now that we have a lead on the area where Adam likely had his eel dish, we need to identify its exact name. This step was quite straightforward: a quick search for `Japanese dish with eel` revealed that the dish in question was `Unagi` (grilled freshwater eel).
> We could have deduced this information even faster by checking the image filename, which was `Unagi_Bowl.png`.
### Pinpointing the restaurant
With a strong assumption that the location was near `Nara Park` and that Adam had `Unagi`, the next logical step was to identify a restaurant serving this dish in the area.
To do this, we used `Google Maps`:
1. Search for `Nara Park` to center the search area.
2. Search for `Unagi` within the region to list restaurants that serve eel dishes.
From this point, the process was simple: I manually browsed through the restaurant listings, checking their images to find one that matched the dish in Adam’s blog post. Fortunately, I didn’t have to search for long as one of the first results looked very promising.
Comparing it with Adam's picture, the similarities were striking!
## Conclusion
After verifying all the details, I identified the restaurant where Adam had his Unagi: `Edogawa Kintetsu Nara`.
Interestingly, this restaurant also goes by another name: `Unagi no Nedoko Edogawa`. However, to validate the challenge, we had to use the name displayed on Google Maps.
