Wangfujing night market--during the day, it's a bustle of shops selling pretty much any souvenir that you can imagine; at night, it's host to a variety of eating a drinking establishments--and food stalls such as this. The customary beef and chicken. All the fixings for some excellent Chinese-style kebabs.
And some seahorse, scorpion, stinky tofu thrown in the mix. Do Chinese eat these? I asked the stall owner through my friend, and was answered with a laugh and a dismissive wave. "Nah, it's tourists who eat the seahorse and scorpion--and I love watching them." But, my friend added, the stinky tofu isn't bad. (I decided to forgo it, myself.)
