We came with a group of 20 during lunch, and was almost refused service because they didn't want to serve a large group that was ordering BBQ. They stated that they only had two nets in the kitchen so they could not serve everyone "at the same time", and that there may be other customers coming in later.
In the end, they ended up with a compromise: we could choose any of the other dishes besides the BBQ. Of course, they weren't served up at the same time either.
I asked a few people from our group that came a bit later to just grab another table separate from the rest of us to see what kind of service they would get, and they were all given their BBQ orders no problem. So it seems like it was ok if several unrelated groups were to order BBQ, but it's not ok if they were all together.
So if you're coming in a large group (12+) to a restaurant called "Yummy BBQ" and are looking to order BBQ, you'll probably want to split up beforehand.
I ended up ordering a bowl of spicy beef soup. There wasn't much beef inside and it had the texture of pulled beef. Comes with a bowl of rice so that you can dip it with the soup, which was ok.
