Hmm… think I’ve seen precisely 1 vegan restaurant in the Paragon (basement, I think), but I think they have a few Sizzlers in the Siam area if you don’t mind gorging on salad. 🤢 😀 

@shaun Now you mention it, I haven't seen any dedicated vegan restaurants in any of the Siam malls, apart from that one you mentioned in the basement of the Paragon. I guess your best bet is to try the food court in Siam Centre (there's usually at least one veggie/vegan stall there).

@shaun Couldn’t believe it when I was in Siam the other day! My favourite Sizzlers (Siam Center) gone!!. 😢 😢 😭 Pretty sure the one at Central World’s still hanging on though?

Yes,I think that one was really one of best Sizzler in Bangkok

I think you see the vegan restaurants are spread here and there in Bangkok, not all in one place. Banana Warrior was very good vegan restaurant which I have visited many times, but it close already some time ago. 

Thank you all!
