David from Grind, a collection of coffee shops, cocktail bars and restaurants, started his hospitality journey by inheriting a mobile phone shop, where he loved the building but not the business. David has managed to walk that tricky operational and design tightrope where his venues are both a great stop off for a daytime coffee, but also a sit down meal, and by night transform into a busy cocktail bar.  Through innovative crowd funding Grind has expanded into some high profile locations.
