I love this place. Every time I come to Austin I go to the Cedar Door - their Mexican Martinis are amazing. They're are a little spendy, but totally worth it. So tasty on a hot Texas day! Their food is good too, nothing too fancy but excellent pub grub/bar type food (nachos, burgers, etc.) The drinks and nice outside seating make it all totally worthwhile. Service has always been quick and friendly even when happy-hour busy.
I just wish they were open at lunchtime during the week!
Pros: mexican martinis, deck, downtown
Cons: not open for lunch, hours strange?
