There's little debate among drunkologists that the moral guilt accompanying a hangover is inextricable from the physical symptoms — sometimes the former rages even stronger than the latter. For example, the effects of dehydration are nothing compared with the recollection of wearing whipped cream in public or bursting into tears at the sight of a wandering cat. The next day's sure cure is a good brunch, preferably with the requisite Bloody Mary accompanying food that will soothe and rejuvenate with its freshness, heartiness and high level of nutrients. Guilt-free for the guilty, in other words. Sustainable salmon, locally grown vegetables, cheese and milk from nearby cows, eggs from chickens roaming free in God's garden — these are but a few ingredients offered by the Westside's elegant Blue Bird Bistro for brunch on Sundays. It's a festival of organic dishes transported to your table in ways that are good for the Earth and easy on the booze budget. Reservations are recommended — this form of penance is popular.
