Each time I'm in Germany I eat a cheap and quick veggie burger at McDonald's.
This time I was happy to see that they took one step further as there's now the Big Vegan TS. It's quiet big, a lot of vegetables, with ketchup and pickles and the steak is surprisingly close to a "real" one, without being too savoury. It's 6.95 in a maxi menu and well worth the price. Overall I really enjoyed it, and hope it will stay on the menu.
