I really like Red Oak for a lunch time option in Oakland. It's usually quite busy, but really is worth the crowd for the food. Also, working here it never fails that I run into someone else from the Oakland workforce so it's always a fun space to catch up with people.
The pick-two option is my go-to. I love the Red Beet Salad and the Sriracha Chicken Wrap. Both have great flavor and it is plenty enough food for me for lunch. The portion size of the full salads / wraps is a bit too much for me, so the 1/2 and 1/2 is perfect! They have serve-yourself water stations and I've had hot tea there before, so my drink suggestions are very limited. I have been there with others who have loved the smoothies though.
During restaurant week they offer a $6 blue plate special, which is fantastic -- always a nice summer treat!
