1. Electronics. No idea about high end stuff since I︆ do not need anything advanced for my duties. That said, there are plenty of general︇ consumer electronic shops (google panafoto) plus a ton of chinese electronic shops in El dorado.︈
Since there many architects & engineers working in the city and they require good computers,︉ im pretty sure you would be able to find what you look for.
2. Available,︊ yes. Expensive, a lot. I buy dutch cheese and spanish fuet. 3x 4x what it︋ costs in Europe. Supermarket groceries in general are more expensive than in Europe.
3. Panamanian︌ food is simple caribbean. (Rice & chicken... Fried fish... Beef and eggs..) Local restaurants are︍ called 'fondas' and you can eat their simple stuff for 4-8 $. Other restaurants that︎ I go to a lot are Spanish & libanese. 25-40$ per person with wine.
4. I am a mediterranean guy and I cook my food 90% of the time. Vegetables,️ eggs, chicken, beef... You can eat the same as in Europe no problem.
5. I dont really like san francisco because its not that walkable. In the city my favourite area is parque urraca. If you want a house with a garden outside from the city for less than 500k you can look at Panama Pacifico. This is where I would live if I had a family. If you need help with this at any time dm me and Ill be able to help so you dont get scammed.
My chess is lame, not even 1000 🙂 but I love playing.
Hope it helped.
