I would open a bakery and bookstore. There would be a small coffee & tea place in the middle of the two. In the bakery, you could buy wonderful breads and there would be a variety of desserts, too. Whatever struck my fancy to make that day would be on the menu. (Hey, if I’m going to dream, I don’t have to worry about the stuff selling. Of course it will sell!) In the bookstore you would find helpful people who smelled like cookies from the bakery. And they would know where every single book could be found. We would easily find out of print items for you, too.
Once you found the book of your dreams, you can wander to the coffee and tea shoppe, get a lovely cuppa, buy a treat from the bakery menu, sit and read your book. Then buy some treats to take home and share with your loved ones.
Barring that, I’ll just go bake stuff for @janbb and @Jeruba, if they’ll have me.
