I discovered Happy Ending Pizza on Burpple Beyond during Phase 2 of Circuit Breaker, when they were a hole-in-the-wall space in Orchard Towers serving only takeouts.
It was a cool October night; I'd ordered 2 pizza sets from them 2 hours in advance. Stood by the roadside eating my piping hot pizza, & I was impressed. The Mushroom Madness & Green Hulk I ordered were delicious, but I couldn't finish everything - so I kept the leftovers in fridge & heated them up the next day.
Guess what? The 2nd-day pizza still tasted good. & that, my friends, was the beginning of my happy ending. They've since relocated to City Gate, where you can enjoy their pizzas with a dine-in experience.
