This is one of my favorite places around.
The staff really makes it a great experience, as they're always friendly, especially to repeat customers. It doesn't take a long time to build a rapport with everyone there, and have a great time! My friends and I come back all the time just to catch up with everyone.
The drinks are pretty reasonably priced, and the food is a solid surprise for a place that doesn't appear to be much of a restaurant from the outside. Your standard bar fare is covered, and is pretty good stuff. Their chicken nachos are the stuff of legend. If you're feeling like something a little more fancy, you can order from the Presidio menu next door.
It's great to have a place like this that is 24/7. It's my go-to bar, by far. Come on in and check it out!
