This is where the locals come to celebrate their nostalgia for the early 1980s. It seems there is a kind of cult around this place that certainly is confusing for visitors. The whole place is stuffed with memorabilia from the past 30 years: postcards, pictures, trophys, souvenirs.
The interior looks a little bit aged (call it patina, or call it grimey if you like) with wooden wainscottings and only two low benches in a small corner. Seems that the general public agrees to buy their sandwiches here, but to eat them sitting on the stairs outside of the shop on the other side of the street.
Please do not get me wrong, I sure can appreciate a traditional place that somehow managed to transport your childhood memories into present day. But I really wonder how nostalgia can obscure the fact that the sandwiches are made with questionable ingredients that come out of army-sized cans and tasteless bread that absorbs every last bit of water in your mouth until your whole throat is clogged up. Good that they also sell draught beer to flush down the sandwiches. Bad that they mainly sell Warsteiner, the worst out of Germany's premium beers. And come on, almost TEN Euros for a sandwich and a beer? You have to look very hard to find a place in any of Europe's capitals where you would spend that much for such a humble meal.
But the worst thing is that the people working here are not friendly at all, it rather looked like our presence had somehow bothered them, maybe because we interrupted them chatting with each other and reading their email.
I think, that looking at the "Golden Egg" without having your pink "nostalgia" sunglasses on, this is just a shabby joint run by grumpy people who sell stuff that you can get anywhere else, better and cheaper.
