About this location
Near Gate M18, this is the farthest-out stop in this batch of Concourse M restaurants, past the four-venue cluster at M16 that holds HUB51, RJ Grunts, Urban Olive and Wow Bao. Doors open at 10am and the bar runs until 9pm, matching Urban Olive's close time but with alcohol on offer, which the counter-service spots back at M16 don't provide. Nothing else in this group sits farther down the concourse than M18.
