Head chef of The Greenhouse is the Finn Mikael Viljanen.[4] Owner of The Greenhouse is Dublin restaurateur Eamonn O'Reilly.[5]
"Connoisseurs" deemed the restaurant worthy of a Michelin star a few years earlier but to their annoyance, the restaurant did not get the award in either 2013 or 2014.[6] The restaurant got its second star in 2020, one of only four Irish restaurants to ever receive that honour.[7]
On 21 May 2021, The Irish Times announced that head chef Mickael Viljanen resigned and joined restaurant Chapter One to take over as head chef from restaurant owner Ross Lewis.[8] As of February 2022, The Greenhouse has not reopened since closing during the COVID-19 pandemic in 2020.
