Cost of Living in Jeddah

My first city in Saudi Arabia! Spent a week there and actually had quite an interesting time. Old Jeddah in the center is extremely cool neighbourhood to walk around during evening, a lot of people around, sounds, lights all around, really liked the vibe.

People are really friendly in my opinion, was given some food treats by random Saudi family nearby in some cafe in the center, have never had an experience like that in many countries I've been to. Although I didn't really speak too much with locals apart from taxi driver and hotel worker. City is not very walkable, mostly very car oriented.
Can recommend to have a walk on Corniche as well.
What I didn't like - I just couldn't find any grocery shop which is not small place owned by Indian with shitty low-quality food, more like rice, ramens and snacks. So basically I had to go out to eat all the time.
