Some things you'll want to consider when deciding where to put your kitchen are: how much space you have available, how frequently you cook, and what appliances you need easy access to. If you're tight on space, you may want to consider putting the kitchen in a corner instead of in the middle of the room. If you like to cook elaborate meals, it might make sense to build in and incorporate another wall with plenty of worktop space and maybe an extra oven; if not having two ovens would drive you crazy then think about adding that to your must-haves list.
