While I too will miss Pirata y el Perico's old menu, I think it's awesome the venue is showing signs of life again. The last time I visited, last Thanksgiving, it was closed. We were pretty upset, as the previous times we had lucked into a MK visit with it running. The food was good and cheap, which was a huge plus.
What is better though is the location. The themeing of the building(s) is beatiful, and a well-themed sit-down restaurant should thrive there. The traffic is much less congested in that area of the park, yet it still is just as heavily themed and vibrant.
I do hope they eventually tie-in the menu better with the surrounding attractions and environment. This could be a little move that ends up as something much larger in scope. I've always felt MK deserved more quality eating options, and this could be a step in that direction. It shows real promise, in my opionion at least.
ALSO: In an unrelated musing, if you've seen Kingsford's latest commercials (running for I believe over 1-2 years), then you are well aware that KS, Lenexa to be exact, is quite famous for its barbeque. Kingsford is a fairly recognizable name when speaking of barbeque, grilling, etc., and I think that if they have chosen to spotlight Lenexa, maybe the Kansas cut of steak really isn't all that confounding.
In addition, menu items really don't always have to be billboards for what it entails. Sometimes just little hints or key words can be much more appetizing, giving you an emotional reaction to the item. It's all a matter of taste, as sometimes I want the full break-down, and other times I'd be much happier with a Pineapple Float.
