I live nowhere close to Phú Mỹ Hưng, the area where you will find Boomarang, but as it is really hard to find enough pavement and fresh air to walk around in the inner city, I regularly go out here in the weekends. I end up at Boomarang pretty much every time.
I tend to get there for either brunch or dinner, this time we were there for an early dinner and we had a Boomarang Burger and a Cajun Chicken Pizza followed by a Toffee Pudding for dessert. The pizza was alright, but there are definitely better options for pizza in Phú Mỹ Hưng. The burger on the other hand was terrific as always, and the dessert was a perfect finish to the meal.
Prices are on the high end for this type of food in Vietnam, but they make up for it with great service, one of the nicest locations in the entire city and mouthwatering burgers.
