During the pandemic there was a number of great pop-up restaurants that appeared in my neighborhood. Perhaps yours too. It was one of the few good things during all the lockdowns. I was especially glad to wander down to the Dai-lo popup on Yonge near Davisville that served a small menu (4-6 items) of delicious Asian food in a coffee shop that was available for them in the evenings. Sadly, it’s gone now, but it was great while it lasted.
A good story on what it’s like to run such a place is here: The Promise and Perils of Running a Pop Up Restaurant | Bon Appétit
Well worth reading, especially if you love pop-ups or thought of running your own. My naive self thinks: oh, it would be fun to have such a place. I have just enough sense to know it might be fun, but it would not be a lark and it would definitely be a lot of hard work to be successful.
