Thank you kindly!
This year I have finally been able to celebrate my birthday on my birthday, rather than being busy with some exam study. Among other things I went to this very geeky cafe. The geekiness started at the front door, which said "Speak friend and enter". The menu items were all various references too. I had a DnD burger, where you roll to choose your toppings, a muggle butterbeer, and for dessert a scrumptious slice of Miss Trunchbull's Chocolate Cake which the menu describes, I quote: "Her blood and sweat went into this cake and you will not leave your table until you have consumed the ENTIRE CONFECTION!". It was a good day.
