Are you looking for any particular type of food? Any price level?
Without any more info from you, I'd think about the following (in order from north to south):
If setting is more important than the food, I'd suggest B*A*N*K. A beautiful room with lots of space to hang out and talk. Bar service is good there too. The food is fine but not spectacular.
Mission American Kitchen is busy and the food's a bit better - a bit of a power lunch scene - but after 1 you would probably be ok and would not be rushed.
Zelo has a nice space and the food is decent.
Vincent has a great lunch and is not especially crowded. Service is great and I would think that they would never rush you out the door. It's not in the center of downtown which is either a plus or a minus depending on where everyone is coming from.
For meat lovers, you could also think about some of the usual suspects: Murrays, Manny's, Ike's.
