I came here this week with a group of 5 other co-workers and we were seated very quickly. There are many tables that can seat 2-4, but not that many that can seat a larger group. Our table had a door bell on it so that we can get the waiter's attention, but thankfully we never had to use it.
The menu is pretty large. The first thing we noticed was that it had a bit of weight to it. I immediately knew what I wanted -- the pork bone soup ($7.99). After a bit of wait, the wait staff brought over some of the appetizers, chopsticks, and a napkin. Unfortunately they didn't bring any plates, so everyone waited until our lunch was served.
The pork bone soup was very good (I've only had it 3 times ever), and it was way better than the PBS at the Owl of Minerva just across the street. There were two large pieces of bone with plenty of meat on it. It comes with a small bowl of rice. I wish there was more rice, since there was a lot of soup. It's definitely salty, but not overly so.
I'll definitely have to give the other dishes a try, but so far Nak Won is my favorite place for PBS.
