Since Łódź isn't lucky to have too many vegan/vegetarian places, this one, situated in the main street, is worth paying attention to.
It's a part of Green Way chain and offers a menu similar to the ones in all the rest of the branches. Food is mostly Asian style, sometimes inspired by Polish cuisine as well. Prices are reasonable, portions really hearty. In a nutshell - a reliable place.
Cons: atmosphere - typical buffet
