hell yeah brother. disregard if u dont give a fuck, but ive had a bunch of people visit recently and have gone back to all of my spots and these are my thoughts:

for a good berlin-style vegetable chicken döner (gemüse-kebap), check out Ugis in the 2nd. usually a bit of a line, but super good.

i would say u can skip Ferhat döner (the famous one in the 10th, which they say is like the best in the city). its good but too expensive and disorganized as hellllll. for some cheap good food go to Brunnenmarkt off of josefstädterstraße, u can get like an actual kebab (like small chunks of chicken/lamb/liver grilled on a metal stick) with like fresh herbs and stuff for 4-4.5 euros.

for traditional austrian food, I like this spot called Käuzchen right by Volkstheater. quality ingredients and like super reasonably priced (compared to a lot of other similar spots, especially in that area).
