The Palo dress code does specify "no capris", however many people read the dress code as what's required for dinner. And the dress for brunch is a bit less formal, for the most part. That said, capris may or may not be allowed, depending on the maitre'de working the door. I've seen them admitted, and I've seen them turned away. If you bring capris for brunch at Palo, be sure you have a backup, if you need it.
