I've been researching for an apartment in Los angeles Area and I've seen countless pictures of kitchens.
Two things come in my mind:
1) I hate cooking alone in the kitchen. At this point, I'd love to have an open kitchen where i can be together with my family or guests, chatting while cooking. Even better when someones come to help doing minor things.
2) What about the grease? My kitchen is closed, I have an excellent hood that exausts the air into the barbecue chimney. It's a Bosch Slimline built in unit but I also use a lot of other appliances out of the stove area (grills, electric pressure cookers, griddles, etc) My kitchen is closed and once in a while i have to wash everything and clean the cabinets and walls with a strong degreaser. By the way, I'm not a messy cook.
My concern is... with an open kitchen, the grease would reach the whole house and settle on furniture, curtains, etc. Wouldn't it?
