CLOSED: One World Cuisine

Previously a standard "pay" restaurant. But these days operates exclusively on "donation" basis. Good concept which has seen the restaurant grow in popularity but has its downsides.
Dinner time you will need to book ahead otherwise you can literally be left standing or miss out. Take aways are now not encouraged (even if you're willing to pay - which is a shame).
Otherwise food is great and service is with a smile.

variety of veggie and vegan dishes buffet style. Currently offering complimentary meals while promoting vegetarianism. This said, donations go towards the continuation of this complimentary meal. "Fake meat" dishes are very good and you can buy many frozen "fake meats". Many people make reservations, but 2 of us came in at 5:30 and were seated!

This is currently the best value vegetarian buffet in all of Perth. I live close by, but it is well worth the trip even if you are not living in proximity to Kardinya. The 940 bus from the city goes directly past it.
