I once went with some collegues to Timeless, a Tex-Mex restaurant in Charlottenburg. On Thursday nights, it’s all you can eat ribbs for 8€, I’m not really into ribs so I did not get them but the collegues who did really liked them.
I had some beef fajitas, 1st good thing: no surprise vegetable, what is written on the menu is what you get. Pepper, onions, mushrooms, tomatoes, guacamole, sour cream, 4 tortillas and delicious meat.
Cocktails are also very nice, service is nice though a little long.
