Noodle Nexus opened up in the tunnels downtown awhile back when I used to work in that area. It became somewhat popular with my co-workers so I gave it a shot. The atmosphere is nice and modern. I'm not sure how to best describe the food -- lots of noodle dishes, and some rice dishes that strike me to be close to Chinese food. I think they are trying to be a Thai restaurant, but that's not immediately obvious by the menu -- there are lots of options. Price is reasonable as compared to other downtown lunch establishments.
