I definitely see the appeal here. I feel like it's more for the masses...think McDonald's, German…read morestyle. And actually the burgers and fries do very much taste similar to that of McDonald's, in my opinion anyway. Even the advertising is in line with that of McDonald's as they advertise huge massive burgers, but in reality you get a thin, perfectly cylindrical and over-seasoned hamburger patty, flat mass-produced buns and misc. toppings...but at least it tastes pretty good. Again...think McDonald's but at twice or three times the price wherever you come from.
If you are a visitor of Hamburg, please do not believe those that say it's the best in our city! There are many more better offerings in Hamburg.
Overall, 2.5 stars. Will you ever see me there again? Not if it's my choice. I won't deny that I thought it was pretty good, but I was disappointed overall. If anything really, it has seriously deterred me from wanting to try Block House.
