I ate here several times. Three times I got the menu of the day- cabbage soup and pasta with tofu (twice) and asparagus soup and pasta with avocado once. I liked the asparagus soup and pasta with tofu a lot. The cabbage soup and pasta with avocado were also decent, but I don't like avocado that much. My vegetable fajita had mushrooms and vegetables and was tasty even though tortillas weren't used. It came with a guacamole sauce. I don't like avocados that much and don't usually eat guacamole, but it seemed to be a good guacamole. I also had the stuffed zucchini twice and it was very good.
I don't recommend the coffee even though they have soy milk, because my cappuccino had cold foam. I didn't complain about it though. I'm sure if I had, they would have removed the charge. But there are other places in Bucharest that are better for coffee with soy milk.
During the day, they have a raw menu and the hot daily specials for 18 or 23 lei. They also have a special menu which originally was just after 7PM but now appears to be all the time. The menu is smaller than the BioFresh in Timisoara, and I hope they can add the other hot dishes found in BioFresh Timisoara.
Note - If you are a tourist like me, you may have ask for the daily menu and the daily menu is also served in the evening (it's not just a lunch menu).
BioFresh is one of the most reasonably priced vegetarian/vegan restaurants in Bucharest and one of the only ones with a menu of the day. They're also fairly good in customer service. When there was a minor problem, they fixed it very quickly.
