The name ‘The Betterment’ encapsulates Jason and his wife Irha’s journey from opening Pollen Street Social in 2011 to today, highlighting the progression of their food, ethos and way of thinking.  The launch marks Jason’s return to Grosvenor Square and is a culmination of all that himself and Irha have achieved in that time.


Jason is passionate about being a restaurateur who supports those who helped him build his company in the first place . One of these people is The Betterment’s Head Chef Paul Walsh, who launched and led City Social for 5 years, winning it a Michelin-star within 7 months of opening.
