I've put the pictures on imgur.com, and each picture also has a caption under it, with some explanation of what you're seeing. More explanation (and my story) below.

As already posted by cdybeijing, Tiandi Jian recently moved (but only about 100 meters). They've also changed their prices, but more on that later. The new location is very nice, and easier to find too, due to the great big sign on the outside. On the sign, Tiandi Jian go club is also written in English, so even those without any skills in Chinese should be able to find it
Also on the sign is the name of the equipment shop they run, called Ben Shou Qi Dao, which translates literally as "Proper Move Game Way", and I guess means something like "Proper style", "Proper strategy", "The proper way to play". Ben Shou is equivalent to the Japanese term Honte. Anyway, they have all sorts of excellent equipment. Beautiful boards and bowls, slate and shell stones, and a large collection of books. And of course a lot of back issues of Weiqi Tiandi. They have a website at: http://www.benshou.com/
When you enter the building, the shop is on your right, using what window space they have. The playing area is behind it. This area is divided into three main sections. Where you enter is the main playing room, with the staffed front desk, kettles to refill your cup of tea, etc. Here, about 20 boards are set up.
Off to the left of this room is a playing room in the Japanese style, with tatami mats and floor boards. It is decorated with (amongst other things) several pictures of Fujisawa Shuko, who visited China often to teach, and is clearly still admired here.
To the right of that, also on the left side of the main room, is a room for official matches, with a single table for the players, and a table to the side of that for the game recorder and referee.
All the way in the back, a hallway leads off to the toilets and staff rooms.
We (my girlfriend Gineke and I) entered around 1:30 in the afternoon, and there were perhaps a dozen players present. We first looked around the shop a bit, then we asked if I could play. No problem, of course. An opponent was found for me, a Chinese 3 dan who spoke reasonable English. When he heard I was from Holland, he told me he had visited there twice this year, on business. From that, and also from the pricing, I gather that Tiandi Jian is probably mostly a club for the richer part of the Chinese playing population.
The pricing used to be 40 Yuan flat fee, but they've changed that at the new venue to an hourly fee. On weekdays, you pay Y10 (about €1 or $1.50) entree fee, then pay Y5 per hour (rounded to the nearest half hour). On weekends prices double, so I payed Y20 entree fee plus Y10 per hour. The entree fee includes a cup of green tea, which you can refill from kettles. They've got discounts from 200 hours onwards, and also membership options (one month, six months, one year and two years), but I guess most of the readers here are unlikely to be interested in that
In total, I spent almost 5 hours there, playing 4 games. Against the 3 dan, I tied with 1 win each. Against two other players, both 4 dan, I also won one game and lost one game. In the end I paid 65 yuan. My girlfriend also paid Y20 (entree fee only, as she didn't play).
All in all, I think Tiandi Jian is well worth a visit for any player traveling through Beijing.
