This IHOP has done it for years (at least 5) and I don't think it will go away any time soon. We used to use it all the time, but now DS12 eats more than me, so no more kids meals for him. It is not a national offer, just one unique to this IHOP. Its every day after 4pm, no particular end time, we've gone about 9pm and still gotten it. Some folks say this IHOP is more expensive than others, but its the only one I eat at so I can't compare.
