About this location
Also at Gate M16, RJ Grunts runs the identical 10am-to-10pm window as HUB51 next door, giving that single gate two full-service, alcohol-serving kitchens rather than the counter setups at Urban Olive and Wow Bao a few steps away. Neither of the two opens before mid-morning, so this isn't a breakfast option — it's built for the midday-through-evening push out of M16, with two separate dining rooms covering that stretch instead of one.
Other options in Terminal 5
All past the same checkpoint, so you can reach them without clearing security again.
