A recommendation from our reporter in the field:
A great pizza place on Uhlandstraße 153
Open late, lots of variety, basically a good authentic pizza.
The 249 Bus stops right in front.

We recently came by across a new Chinese-Malaysian Restaurant called the Green Lotus.
Münchner Str. 25
http://www.green-lotus.de/

Direct on Bayerische Platz U7/U4

nice atmosphere, real authentic food, home-made hor-fun (flat noodles) and an excellent selection of teas.
also some good dim sum
lunch menu available

Holländische Snackbar

When you need a french fry/fried food fix, go here.
Nice place to sit and a large selection of sauces.

5min walk from Ostkreuz

Sakorn Thai cafe

Located on Kant Str. close to the U7 Wilmersdorfer/S-Bahn Charlottenburg, or M49 X34 Bus lines.
Kantstraße 105, 10627 Berlin
It's an authentic place, with mostly Thai customers looking for a taste of home, or the occasional american expat looking for his southeast asian fix.
Every dish is 5€!

The food is some of the best Thai food in Berlin and the price is unbeatable.

AREMA
http://www.arema-restaurant.de/
located by the U9 Birkenstraße, right at the exit.
Nice pleasant european breakfast!
cheeses, butter, schinken, salami and a bit of fruit etc.  YUM
The rest of the menu looked interesting like the flammkuchen, but one can only eat so much...
Good service, nice atmosphere, good food.

Sorry everyone for not keeping this blog updated, but let's have another go then!
One of the best if not the best Hummus in Berlin.
AZZAM Sonnenallee 54, 12045 Berlin
http://alarabonline.de/restaurants/azzam/index.html

 Take the U7 to Rathaus Neukölln and walk.
 Prices are great and so is the atmosphere.
 In addition to awesome heavenly Hummus, the other dishes are great!
