Cinema at the edge of Beckton, in a small shopping precinct just off the A13. Despite its name, it's at the very border of the London Borough of Newham.
With 14 screens, it's very large and rather soulless (it seems to be going for a 50s vibe), with the obligatory bowling alley attached. It is at least spacious and clean inside and staff are friendly, if perhaps undermotivated. Screens are comfortable with seats that recline slightly. In case you want to see the latest big films, it's the only English-language cinema for several miles, and is the only Showcase cinema in London (for those thankfully rare occasions when only Showcase is screening a film).
It is served by the 325 and 366 bus routes (and close to the 173), but it's clear from the parking space that you're expected to drive to get here. Go to the A13/A406 junction, take the eastbound A13 slip road, and turn sharp left about a hundred yards after the roundabout, then circle round to the right. Alternatively it's a half-hour walk from Barking Station but you need to be attentive to the map.
