First things first: I work at Gutburgerlich... Thanks for the nice review, Tank, I'm glad you liked the food! Just one little thing: The falafel (vegan) is prepared in a deep fryer with vegetable oil. The Portobello mushroom (vegan) and halloumi (vegetarian) patties are fried in a pan which is only used for veggies and said patties. They won't touch any meat while prepared for the burger! From time to time we will fry a vegan/vegetarian patty on the meat grill but only with your permission. It's a little faster, so for example, if you are in a hurry, we will ask if we can use the meat grill to get your burger ready as fast as possible :)
