During Fete de la Cite organized by the residents of Maison de l'Inde in Cite Universitaire in Paris, there were food stalls in front of the building. It was open for everyone. The people manning these stalls were kind enough to let me inside the stalls so that I could shoot the expressions of the visitors, who were there to check out the food. It turned out to be an interesting experience.
The food was colorful. That is what attracted a passerby to the stalls. There was a clear pattern emerging when I observed the behavior of the visitors. First, they were surprised, then intrigued. The intrigue leads to questioning. The questioning results in answers. Then, the expression in the face changes. Some want to try it out which is usually indicated by the smile on the face. Some are still skeptic.
Here is one picture which I captured after the questioning phase. The expressions are for your interpretations.
