344L: Brother and Sister Run Amuck Through Restaurant

My book Stumper is a children’s book that I predict comes from the 90s (even 80s maybe). I had it read to me everyday when I was a kid (I’m 22 now).

I have no idea what it’s called, but the cover depicts night time (Navy blue) with a restaurant illustration! I remember the book being rather large and rectangle (long). To give you a visualization, it sort of resembles Van Gogh's “Cafe Terrace at Night” painting!

The book follows a brother and a sister who run amuck through the restaurant - they run through the chefs kitchen and hide under the tables. They also do a lot of magic tricks. I vividly remember a white rabbit in a hat and the extending handkerchiefs!

The girl has black hair in a short haircut, and I can’t remember what the brother looks like.

I suspect that it’s not a popular childrens book as I’ve looked at countless lists and it’s never been there!

If you can find this book, I will be beyond happy. I have literally been searching for it for YEARS!

259A: A shameful delicious lunch (Solved)

My query is on a book I read in the mid 1960’s, however I don’t know when it was published.  It was a child’s book about a young student (I  believe a girl)  whose parents worked in a restaurant.  Because of that, she “had” to bring lovely, delicious restaurant leftovers for her school lunches.  I vividly remember the descriptions of her covering her desk with a checked cloth, and taking out all this elegant, gourmet food.  The twist was that she was ashamed of her lunches, for being different.  I hope you can help!
