Is it OK for bars or clubs to offer a happy hour early in the evening to get patrons going, then turn up the heat and make it hard to find water so those patrons keep ordering more drinks and getting more and more drunk throughout the evening? You honestly believe we need a law against this? God forbid a restaurant owner offer any promotion whatsoever.
(Note that I am not the person you replied to.) I do honestly feel that there should be a law against that in the society which I live in, since I find such actions taken by the restaurant owner to be manipulative and purposefully deceptive (excuse me for not coming up with better terms, I am not a native English speaker), knowing that many people -- not all of them, but many -- thus end up drinking far more than the…

The property owner may deliberately arrange the environment so as to maximize an expected consumer end. There is absolutely nothing wrong with this. Supermarkets are architected to encourage higher shopping. Clothing retailers will arrange their luxurious brands to have a higher aesthetic appeal inside their stores.
Taking your logic of needing to regulate any "misleading action" to its conclusion will only entail the abolition of the market economy. There's no way around this. Anything and everything can be shoehorned under such flimsy logic.
(Moreover, expecting that consumers are morons who cannot regulate their own behavior will generally lead to policymakers drafting proposals that assume as such and end up fulfilling the prophecy on their own, since the resulting bureaucracy will be internalized by consumers in their expectations.)
