To clarify - I have only tried Uncle Testu at the Front Street Market. I enjoyed it. It was light and fluffy and not to sweet.
That being said I wouldn't wait an hour for an entire cheesecake. So if you also dont want to spend your day in the heat with a bunch of strangers - go to the market in front of union station! not only is there no wait, but you can also just get a slice vs committing to a whole cake and then feeling sorry for yourself if you eat it all
