Ask Americans about their heritage and almost invariably they will mention some distant Irish or Italian ancestor who fled the old country during a famine or riot or depressing film festival. Reconnecting with our Irish roots is a simple matter involving buckets of whiskey and a bloody brawl. Finding the inner Italian, on the other hand, requires more authenticity. Arcodoro & Pomodoro prepares true Sardinian cuisine in a space designed to mimic the rustic elegance of an Italian street-side cafe. More important, they serve grappa--more than 12 varieties--and other traditional liqueurs. Nothing says "I'm Italian" better than a day spent sipping the vicious remnants of the grapevine, bottled neatly and served in a deceptively narrow glass. Grappa packs enough wallop to put hair on a woman's upper lip.
