On our way from Shimokitazawa to Shibuya we stopped at a place called Bondi Coffee Sandwiches, because we heard that they also offer vegetarian food. They mainly serve sandwiches and one of them is vegan. It was very yummy and the vegetables really fresh. Though for about 600¥ or 700¥ (I dont remember the exact price) it could have been a little bigger or with a little more stuffing. The shop itself is really beautiful and you can also get smoothies and fresh coffee, which looked really good! If we pass by again, we will definitely check out the drinks! :)
We did a little trip to Osaka and found the delicious Izakaya 海だるま near Nanba station with awesome vegetarian options!! The Izakaya itself was very beautiful, so it was very nice to spend an evening there! We went with a friend who eats meat, he was also amazed by the veggie dishes and the fish. They also have an english menu, so its no problem to understand if you can't read japanese :) !
If I go back to Osaka, we will surely spend another night there!!! ^__^
If you want to eat a vegan or vegetarian burger in Tokyo, Island Veggie in Shibuya is a good place to go to! It's more expensive than Freshness Burger, but therefore you have much more options, the quality is better and the size a bit larger. The burger cost between 900¥ and 1200¥. I chose the the one with avocado and my friend the falafel one. The homemade lemonade was also very refreshing :) !
