Canteen is a thoroughly middle of the road restaurant. The food isn't bad, but it's also not particularly good. I was expecting more from an O&B joint. Prices are reasonable, which was a nice surprise. The interior is also quite nice. It's probably a better place to meet for drinks and appetizers than to meet for dinner proper.
They do look to serve a slew of sandwiches, so I will need to go back to see how the place fares as a lunch joint.
