How do you calculate restaurant food?

Hi,
New here. I just had lunch at an Ethiopian restaurant and have no idea how to calculate the calories in my meal.
I had a dish from New Guinea called Poulet a la sauce d'arachide and Fasolia.
????
I also had a piece of cake.
Hmmm....I can at least estimate the cake but have no idea about the other stuff.
Googling the dishes did not yield results.

I know "poulet" is French for chicken, and I googled "arachide" and got peanut. Chicken in peanut sauce? Does that seem right? I found results for fasolia... white beans or green beans. Did you have either of those?
