This is essentially a cafeteria catering to the employees of the Federal Procurement Agency, which is located in the same building in the midst of an industrial/commercial park. "Das frische Bistro" is also open to external visitors. It offers two, and occasionally more lunch options every day at a price point of EUR 6.50 or EUR 7.50, and one of those will be vegetarian.
Unfortunately, no cards are accepted despite the fairly remote location where the next ATM is more than five minutes' walk away. If you are visiting the Procurement Agency, you might receive discount coupons from the reception attendant. These can be used here.
From what I've eaten I think it's a pretty mediocre place where the interior is nicer than the food. It's freshly made but very much on the heavy side, just look at the massive layer of breading on my piccata. Not worth a detour if you're not spending time in the area anyway. (Granted, providing high quality German or German-International food on a budget is quite difficult.) read more
