People still reply since the quest still exists and this is a useful guide.
FYI, after doing some searching I finally was able to find part 2 of his guide... title= [Guide] Instance Strategy-Magic kitch path(part2)
I didn't find the 2nd part of the guide until after my friend and I reached the door to the kitchen telling us we need to get the key... /yct03 in his guide he as a shortcut on getting to gulp room, but we are going to have to do it the long way since we decided to do gulp room another night by then it was past 3am /f75
If you decide to do the long way, going through gulp room, he has another guide titled: Instance Strategy-Gulp room
get up to the chest, get your key and then go back to the magic kitchen to kill your annoying Beelzebub. Once that quest is done... you'll be able to get the Gulp room quest which has even more fun /f87 monsters/bosses to kill.
If you want to have a better idea of the bosses and monsters for the kitchen quest, there's another useful guide titled= [Guía] Magic Kitchen Path. Note: This one is in Spanish, but even if you don't understand Spanish, there's lots of pictures to help give you a better idea of what is going on /yct63
Good luck to all that are trying this quest... I know I couldn't do it without the help of my higher level friends... I heal while they kick behinds /f50
