i have to say that what has been suggested for a tip so far is way above what we leave as a brunch tip. we have not done many brunches as i'm not a fan but we have left $15/$20 for the two of us, not each. now dinner is different. we have not done many of those either (palo is not my favorite but that's just me) and then I would tip $10/$15 p.p. depending on the service.
guess i'm in the cheap seats.
