i was going to mention swingers in hollywood or santa monica, but i see that's already been mentioned.
if you are ever near eagle rock, the table cafe has some vegan options. and it's also right across from fatty's & co., which only has vege food, and in my opinion is a little overrated.

but back to the table bistro, they have vegetarian options and a few vegan options.
