I'm sure we can find room for a few more decorations or food items. I reckon there should be space for a hyperspace-annexe through that full length mirror next to the "Ladies". Just do us a drawing with the dimensions (and how many dimensions you want it to exist in) and I'll make a start on the construction just as soon as I've finished laying my new kitchen floor tiles.
In the meantime, I'll have a pint of sloe gin to celebrate my birthday.
Quack!
