cool spots in duisburg? (specialty coffee, vegan/vegetarian food, alternative scene)

i'll be working in duisburg a few days a month and want to actually explore the city a bit, coming from berlin

looking for recs on:

• specialty coffee

• vegan/vegetarian food, casual spots not just "has one option on the menu"

• alternative/hipster scene, bars, record shops, vintage stores, anything with an indie vibe

• other stuff locals actually like, markets, events, hangouts that don't show up on tourist lists

thanks :)
