For me, food is secondary to the experience, atmosphere, the people you are with, the memories it brings back.
One of most memorable was a road side cafe in India. We had been travelling all day and absolutely starving. Place was a complete dive and you have driven past it 99.99% of the time. Food was very simple, potato curry, chappaties, rice and dhal. Flies everywhere and not a pleasant smell from nearby sewer. But at that time the food was like nectar, had a view of an amazing sunset and great company. It was just one of those 'moment' things where so many things came together for that perfect moment.
