Hi, sorry for the late post, I've been traveling...
At Katy's the chicken with hot dried pepper and three pepper chicken are two separate entities. The chicken with hot dried pepper is similar to salt and pepper chicken fried with the dried peppers, offered at many Sichuan places. The three pepper chicken, which is not on the menu AFAIK, is similar to LSC's Tony's three chili chicken in that it has a sweetish sauce. And I don't think they offer three pepper chicken on the lunch menu.
And as ordering outside the menu is a little dicey due to the slight language barrier, it's sometimes a dice roll if you actually get the dish. Good luck though!
