Brahmi's Kosher Vegetarian in Van Nuys/Reseda?
I've been there a few times, since I'm a vegetarian and it's right around the corner from my house. The pizzas and calzones are actually quite good - they use a lot meat substitutes like fake pepperoni and fake chicken made from wheatmeat. The lasagna was also good. They also have a unique non-vegetarian pizza that's popular in the UK and in Israel - tuna and corn.
It's run by orthodox jews, so they close at 3 PM Friday and and are closed all day Saturday until 7 or 8 PM.
