At the last minute I'm taking a friend out for his birthday tonight. He wants "fun or celebratory" whereas most of the places on my list tend towards "quiet," so I need some help. I'm thinking Otto, with Bar 6 as a backup in case the wait is too long. Any other good backup plans in that area? Or other thoughts below 14th street (doesn't have to to be as casual as those 2)? Looking to spend less than $60/person. We eat most things but I would like to stay away from Mexican.
