Looks like they just opened earlier this month if the Yeip reviews are any indication. I just noticed them recently as I zoomed by. They are located by Waterloo and City in the old Big Time Harvey's spot.
Menu looks like another gastropub with heavy focus on drinks. They have valet up front. Will have to give them a shot when we get a chance. Not surprised at how Big Time Harvey's not lasting long, am surprised how fast they got Corner Door in there.
