Hi Natascha,
I was hoping to hear from you. I will take your list into careful consideration. What this means (in Klartext), is that I’ll get to each of the addresses I possibly can. The thing is, we’ll be traveling with friends for part of the time, and other people tend to have their own ideas.
In any case, eating a cheeseburger at The Bird is the main reason for this trip to Berlin, even though my wife thinks that it’s because we want to see Nefertiti. I’m sure I’ve heard of Wirshaus “Henne”. It was probably in one of your posts, either here or on Chowhound. And Friedel Richter looks great, too. Although the idea of paying in Bitcoins is a little intimidating. All I usually carry with me are Euros. As far as Txokoa is concerned, you mention the 24-hour pork belly. I looked at their menu, and they also have 36-hour braised pork cheeks. Have you tried them?
We’ll be in Berlin the first week of May, so Thaiwiese is a definite possibility. And market at Winterfeldtplatz with Thai dim sum is not to be missed. The last time we were in Berlin we had some quite nice Vietnamese food in Lichtenberg. Do you know the place?
