for food:
"Falafel in berlin.de" at U Görlitzer Bahnhof (Falafel plate say to make it vegan)
"Ahn Dao" at U Eberswalder Straße
"The Butterfly Lovers" at Brunnenstraße
for nice city impressions:
*sightseeing day*
start at Zoologischer Garten, take the bus 100 all the way to Alexanderplatz (follows one of the tour busses without the price), you can walk back from there past "Museum's Insel" down "Unter den Linden" and turn left after "Brandburger Tor" and pass through the "Holocaust memorial" (please be mindful here, it's a place of memory. even if some treat it like a fun insta location). at Potsdamer Platz have food at "Saravanaa Bhavan Berlin" (south Indian cuisine, vegetarian with many vegan options), then get some donuts at "Brammibal's Donuts" (you probably have that on your list already ;) )and enjoy the view from "Panoramapunkt Berlin" (way cheaper than "Fernsehturm" and still great).
Alternatively you can get of the Bus at "Bundestag", Walk across the "Tiergarten" to "Potsdamer Platz" an take that walk backwards.
*Berlin Life day on bike*
Start at Ostkreuz with bikes(!) don't attempt to walk this. Alternatively use public transport. Cycle around "Stralauer Island" and then along the water past the "Molecule Men" all the way to "Oberbaumbrücke". Lock your bikes and walk up and down "East Side Gallery" (old Wall with graffiti). When you are back at your bikes, cycle across the river and follow the train tracks up to Görlitzer Bahnhof. Have Falafel (say you would like it vegan). Pick up a bottled drink at one of the "Späti" shops (corner shop) even alcohol is allowed. Continue along the tracks to "Prinzen Straße". Turn left and continue until you pass over another river "Landwehrkanal". Turn left, right behind the bridge, sit in the park and enjoy your drink. There put "Vux" in your phone and cycle there for tasty vegan cakes. Afterwards, again with Navigation, cycle to "U Leinestraße" and from there to "Tempelhofer Feld"(to find it: you will likely see a lot of people walk and cycle down a parc-like path opposite the corner of "Thomas Straße"). When you get onto the old airport field turn right and walk to the community garden. Walk around in it and enjoy what people build because they felt like it. Afterwards cycle across the air field. It's a very freeing feeling :)
If you want to do something in the evening, i recommend going to "S+U Warschauer Straße" and across the "RAW" area.
You can start by having either (1)vegan sushi from "Secret Garden" (2) Döner or other fast food from "Wat is mit vegan?" or (3) are bit further in the area "Emma Pea". Afterwards it's just a nice place to experience, similar to the "Tempelhofer Feld".
