Not sure about others, since it's a rather broad scope really, but personally I'm usually found at school, or at home. I have little reason to 'go out' and 'do' stuff. My entertainment's mostly from interaction with people, and 'doing' stuff 'out' tends to just distract me from such. On rare occasions I can be found at a tim horton's (doughnut / coffee shop a la soviet canukistan), but only if there happens to be someone there who I want to actually speak with for awhile, which's rare since I'm especially shy in person.
As for cooking, I cook quite well. I bake well enough. I don't care for cooking steaks/hams/meats in general XD
My idea of food is something that's got a sliding scale of complexity (say... pasta sauce) where yeu can either go simple (sauce, that's it) or ramp it up for flavour by changing around or adding ingredients. I prefer to be able to have quick and easy to make meals, that taste good, and are filling, and healthy. Subs, pasta, pizza, stuff like that can be heavily modified to fit one's taste palette easily, and can change based on how much effort yeu feel like putting into it.
Keep in mind, that I also think food should be powerful in flavour as well. It doesn't have to be spicy, or hot, or whotever, but those are available options. Garlic and cayenne are <3 I just hate the idea that yeu can be munching on rice idly while talking to someone and clean yeur plate off and be like huh... I ran out of food, and not even notice yeu were eating it. I like stuff that yeu stick in yeur mouth and it knocks yeu onto the ground then jumps on yeur prone form. If yeu don't know yeu're eating it, yeu're doing it wrong >=O
Anyways, not sure where other ENTP's hang out, but I imagine either with close friends, (for me this's mostly online), or places where they can find some kind of stimulation, generally intellectually.
