Happyfield’s Happiest Meal.Jennifer SooThe vibe is sunny,the theme is North American diner and the food is fast (these days,a one-hour turnaround and you’re out the door). From fat cookies to pancakes drenched in maple syrup,Happyfield spreads joy by the tray load. Now more room next door and an expanded menu combine to make even more people happy,while Single O coffee,ice-cold beer,espresso martinis and negronis turn weekend brunch into a pancake party.
