I agree. Guinness world records for things like this should probably not be taken as authoritative since they are heavily skewed by selection bias. It seems completely implausible that there aren't any vegetarian restaurants older than that in parts of Asia (especially in religious communities of Buddhists, Jains, etc.) where large populations have been practicing vegetarianism for many centuries. Even if you rule out things that aren't "continuously running" (whatever that means in practice) that seems quite unlikely.
