In addition to the fact that The Naam is open 24 hours (which is rare in Vancouver), the food is awesome. Even meat eaters tend to enjoy the food here, and the atmosphere is really relaxed. The menu options are diverse, and they are all delicious. You can also spend a great night here with booze and friends.
The Naam, in addition to being delicious, is also historic: it is one of the first veg restaurants opened in Kits, and it is probably one of the oldest in Vancouver. The menus include a lot of history about the role it has played in shaping the neighbourhood/community.
If you have a large group, and are not paying together, start paying your bill well before you are done the meal. Otherwise, you might wait forever.
