if you are invited to a dinner party and
a) have been asked to prepare something for the meal
b) have special dietary restrictions
c) would like to surprise the host with a treat
you shouldn't expect use of the hosts' kitchen. they are preparing a much larger meal and you will be in their way. dont stress them by asking where this/that is or to move over and make space for you.

check with the host first about the availability of their kitchen/stove or bring something that is fully prepared and needs minimal attention.
