I went to Stella with a friend because she told me there would be a vegan breakfast. Not easy to find in Stuttgart if you ask me.
I had a nice, fresh pressed, orange juice and ordered the "Veggie Breakfast".
It contains vegetables as cucumber and carrots (fresh), zucchini, carrots, mushrooms, eggplants (grilled), two hearty homemade spreads, a chocolate/nut spread, marmalade, vegan butter and lots of and different kinds of bread.
Really really good!
My friend told me that a vegan cook (Katharina Bretsch) is working there, and if you look at their facebook page it seems they also have vegan lunch options and muffins, I haven't tasted those but with Katharina Bretsch having released at least two very popular vegan cookbooks I'm very confident it all tastes yummi!
Staff is nice and the location is the right mix of comfy, personal and neat.
Cons: servers meat
