Good food - but sharing is essential!
I've been to the noodle bar twice. I had the ramen both times - the broth was heavy and very flavourful. During the first visit I had an entire bowl to myself, which I thought was too much. The second time I shared with others and I enjoyed it a lot more. The pork buns were delicious, as many other people have written. I also really loved the onigiri (rice balls) but unfortunately, they're no longer on the menu.
The milk bar upstairs is also worth a visit, although I've only tried two things, both that I enjoyed. First, the famous crack pie. It tastes mostly like a sugar pie (ie. it's very sweet and tastes of butter and brown sugar) so sharing it with others is ideal. The second item was the soft serve ice cream that can be ordered just at the cash. There are two flavours: cereal milk, which has a bit of a tang, and coffee. I suggest getting a mix of the two and asking for the corn flake crumb. It's a small portion for a hefty price (about $7) but as a one time treat it was a delight. I finished it in a matter of minutes.
Overall, service was average, there's nothing I would complain about. I'd definitely go again with a big group of friends to try the rest of the menu.
