We’re sorry for the bad experience but if you see that the restaurant is empty it doesn’t mean that it will be for long time. We need reservations, I’m sure that the waiter told you that you could have just 25 minutes because you came in the weekend and the time slot for lunch starts at 12:30, it was all fully booked at that time. That’s the reason. The reviews for a vegan restaurant are really important and I think it’s not fair to make a bad review because you didn’t book for lunch. If you did it, you could have the chance toto read online all the time slots info. The restaurant is too small to come without reservations, sorry for that. :(
