For those wondering about vegetarian food in Samara...
It's relatively easy to find restaurants that offer a few vegetarian dishes. There are also quite a few Italian restaurants in Samara, or restaurants with Italian options, so that's always an easy backup.
We came across one all-vegetarian restaurant, and whether you are vegetarian or not, I highly recommend trying it out! The restaurant name is Ahora Si. It's located just across the street from Casa Esmeralda. It's an all vegetarian restaurant run by an Italian lady who makes everything from scratch. Great food at a reasonable price!
