I've been there twice since discovering it, and I've been very happy both times. The first visit I had the falafel burger, which is more do it yourself than the name suggests, with an excellent amount of falafel balls, two pita breads, tahini, cucumber, tomato and lettuce. This was really satisfying and pretty great. The second visit I wanted to try the chili pasta, but sadly they were all out so I went for the mushroom burger, which is a mushroom patty (rather than a whole mushroom, as I thought it'd be) on a wholemeal bun, with coleslaw and wedges. This burger was so good. I am absolutely going to be eating this again, it was filling and hearty and way more than I was expecting.
The cake is good, even the next day. No photos because I got it takeaway both times; once, I had the carrot cake for breakfast (in bed at the hostel after a tiring day of cycling: no regrets); the second, I had the chocolate cake after a hard day of cleaning and moving in to my new apartment. Aside from the large dollop of (vegan) cream, it was so good. I had considered calling my travelling blog 'the year of no cake,' because for the most part Chinese kitchens don't have ovens so I thought there'd be no cake for vegans; I'm so happy to declare it's not true. There is cake for me.
The menu is in English, and some of the staff speak English. Open Wednesdays to Mondays (closed Tuesdays, as I learned the disappointing way today). Service can be a little slow, but not overly so. Sometimes greenie and vego events are held there.

Take Line 2 or 5 to Yonghegong station, exit D. Head North from the exit towards the second ring road, and turn down the tiny alley way immediately there. It's about 150m down, on your right. Three stairs up to enter, and awkward double door and hard to manoeuvre. Good lighting.
