Dragon Castle

I've only been here during the daytime, in part because the area (and in particular the tunnels around the roundabouts) isn't so inviting during at night, and in part because the dim sum is what draws me here.

The restaurant itself is easy to miss, as there's nothing that screams 'chinese restaurant' until you get to the two big red doors (which are always closed). The decor is simple inside, with large windows letting in a lovely view of the Walworth Road.

Pluses
+ the dishes are cheap: we once ordered so much that we couldn't see over the steamers
+ good selection of dishes, with some more fusion-inspired specials (these don't always work)
+ you can book a table, which is rare for good yum cha
+ the restaurant is large enough for a table of ~15

Minuses
- service isn't particularly friendly
- no trolley service (although this is the norm for london)

In all, I'd recommend this place for yum cha, especially for those with large groups of people who don't mind travelling from the usual dim sum hotspots to avoid a queue.
