ABC American Buffet Corner, Velp, Netherlands

Crazy buffet combination of 9 buffets: grill house offering everything from steak to spare ribs, fish grill with all kinds of fresh sea food, Chinese wok and buffet, Sushi buffet, Salad bar, Soup bar, Bread counter, Italian buffet with fresh pasta and pizzas and a seriously huge sweets corner with cakes, ice cream, fresh fruit, pancakes and waffles made to order and even cotton candy.
This is especially suitable of large groups where there's no agreement or compromise possible between the different tastes. Here you can keep both vegetarians and carnivores content. Meat and potato people can dine next to the adventurous types who don't scare away from sushi. Beware of sugar-induced hyperactivity when you bring along kids. They will usually entrench themselves in the dessert section alongside sweet-toothed adults.
You do need to reserve. All you can eat including non-alcoholic beverages is about 26 euros.

Khan, Mongolian - Chinese Wok and Buffet in Goch, Germany

Large selection of meat, fish and vegetables as well as Chinese dishes. Includes special items such as kangaroo and scallops. Very affordable. All you can eat for 14.90 euro per person. Drinks are charged separately.

I posted this earlier without a photo. This evening after enjoying yet another dinner with friends, I finally remembered to take a photo. The buffet on the left features Chinese dishes, dim sum, fruit and dessert. The buffet on the right offers a huge selection of fresh vegetables, seafood and meat for the Mongolian grill at the far end. This is the fresh wok buffet which allows you to heap a plate with your favorite vegetables and seafood/meat topped off with your choice of seasoning (freshly chopped garlic, ginger, red peppers and a choice of sauces). When you're finished assembling your wok plate, you simply hand it over to the wok chef standing at the grill. Moments later, the sizzling hot wok meal is brought over to your table.
