Zilli Green looks like a great option for a nice vegan dinner, but sadly turns out to be the worst one for vegan food in the area. For a pretty high price you get okay veggie food in small portions that - in most cases - will leave you hungry for at least their less-than-stellar dessert if not for the nearest falafel on your way to the tube.
The somewhat nice and "green" interior doesn't really make up for the fact that this place actually caters to the "culinary curious" or "health conscious" omnivores rather than to actual vegans. If your date is vegetarian don't be surprised to find dairy products on your shared vegan plate for two or the occasional milk chocolate item in your dessert. Don't order in italian if you speak the language, you might miss the fun conversations the staff is having about you or other guests.
We gave this place a second and third chance but were disappointed every time. It just recently ruined valentine's day for us with a nicely burnt main course and 25 minutes waiting times between every course of their "valentines menu".
Oh and did I mention the charge of almost 12% gratuity/tip by default and the really hard time they give you to take it off the check? I mean after all, this place is part of the Aldo Zilli empire ...

Cons: small portions, unfriendly staff
