Went there again on October 22nd, 2015. I ended up ordering a little earlier than my arrival time by ordering through Ritual app.
I ordered 1 pulled pork bao (spicy option), jerk chicken bao (spicy option), and siu mai. Although it was pretty late in the day (around 6 PM), they had some siu mai available. It wasn't bad, but it wasn't super fantastic as some people say. The funky taste was less than that of the shrimp dumplings, though.
Pulled pork did not have that nasty, slimy stuff this time and jerk chicken was also pretty tasty. Turns out the spicy sauce option just meant that they'll put Sriracha sauce in there for you, which can be convenient. For me, it felt like it interfered with the taste a little bit.
