The Brauhaus Lemke is not the only micro in Berlin situated in railway arches, Brewbaker, next to Bellevue S-bahn station has done the same. Just a few stops from the centre as well, in a quiet area with apartment buildings and parkland.
Very quiet if you ignore the rattling of the train. Some tables outside, inside they have just one arch – Lemke has two. Three beers of their own plus a guest, currently Weienstephaner weisse, which would be a welcome guest most places. Food menu, too, both snacks and more substantial meals. I think you are frowned upon here if you do not offer some kind of food to go with the drinks.
The beer were interesting, each in their own way. A grapefruit weisse was very refreshing, the bitterness of the grapefruit playing with the light wheat beer. Smooth and easy drinking, a fine summer refreshment – and something very different form the grapefruit lemonade/beer mix being sold in bottles.
The Berlinsch is a homage to the Kölsch of Cologne. This beer has a lot of flavour. A bit sweet, but with hops giving both flowers and bitterness. A fine session beer.
Their Bellevue pils was, however, the best of the bunch. Well balances, soft mouth feel, crisp dry aftertaste. I ordered a large glass of this after finishing my sampler. This was probably the best beer I had in Berlin.
A few minutes walk from Lemke there is another brewpub, which I believe is under the same management. This is even closer to the Alexanderplatz, located on the first floor of a shopping centre. I sat outside on the terrace, in the pub itself you have a sort of mock Bavarian bierstube concept, while it is open to the galley of the shopping centre showing another kind of reality.
A few hundred metres from the busy Alexanderplatz in central Berlin there is a brewpub well suited to have a break and a refreshment. 
Nice that there are other uses for such premium space than junkyards.
The arrival hall of any airport is not the place where you’d choose to spend time. You’d be there waiting to pick up friends or relatives, hanging around waiting for delayed luggage, that sort of thing.
After a few brief minutes of getting myself oriented, I arrive at the Südstern and is met by a lovely smell of malt drifting out from the open doors onto the terrace in front. I find myself a table and soon have a glass of each of their regular beers, the Heller Stern and the Dunkler Stern.
I feel a wish for a snack, and iI discover an Alsatian speciality I haven’t had since I was in Strasbourg circa 1988,
