Hiddy, you are correct, vegans will not wear leather shoes or boots. Nor will they wear garments made of wool.
Porridge with milk is not an option unless it's made with soy milk.
The asparagus dish sounds lovely and something we will definitely try, I have not noticed it on the menu before. Can be followed by the fruit platter, and if you add things from the salad bar might make a pretty decent meal.
