Must know places in JLM & how to run your economy

Hi, I've been doing Aliyah and living in JLM for the past 3 months, it is a city with a lot of personality but I feel my lack of knowledge about hebrew and a lack of confidence in regards to going out has left my knowledge about the city somewhat limited.

So because of that I'd like to asj in regards to certain kinds of places to to, like the "if you live in JLM you must go/be aware of X place" :

- Clothing (I'm male, and I'm interested in everything but mostly tshirts, shirts, jeans, coats and simple clothes you don't mind ruining at work or the gym)

- A place to get a good sturdy backpack

- Places for footwear, mainly dressing shoes and sneakers

- Places to buy tech stuff or go to if something like my phone is broken.

- Good food places to go to or order from (I'm good with it being not kosher)

- Good pub/bar

And now to keep a good budget, I'm currently getting the sal klita which is not a lot but for reference, to my understanding an average salary is around 8000 shekels right? How should I split it?

Hypothetically I'm living on my own and renting a place, I understand rent is around 1500-4000 shekels depending on what you're going for. How much money is necessary for having enough food all month? When does it become excessive spending? How much money should I allow at most in say going out? Either partying or drinking and so.

How should I split (roughly speaking) my spendings?
