55 Mercer will likely end up as cream of the crop. But Theatre Park, Tableau, and PJ Condos are also good ones in my books. Also have a soft spot for one of CentreCourt's earlier projects, Peter Street Condos.
Tableau works as a sort of shockingly modern contrast to the surrounding heritage (or what's left of it); PJ was so close to really, really good, and then ......then....the ground floor happened. Sigh.
