I often end up at CRAFT for group events or work related things as they are really good at accommodating large groups. They have an upstairs area that can be sectioned off for private parties and there's some good spaces for large groups on the main floor as well. Since they are just a short walk from many of the office towers downtown they're well located for the downtown crowd. They have a great selection of beer, although I must have bad luck because they are usually out of my first or second choices and the food selection covers most of your typical bar fare, they also offer brunch which have tried as well and it's pretty good.
