Tack an extra digit onto your SAT scores. Valhalla is a grad student-run bar tucked into a corner of the old chemistry building on Rice's abundantly treed campus (look for the red arched door). Even without the verdant surroundings, Valhalla's ridiculously cheap 75-cent beer is a sufficient lure for anyone interested in the effects of ethanol on the human body. The bartenders are volunteer Rice staff, faculty, students and alumni. Out on the lawn, perpetual doctoral students and their families lounge on the grass while their four-year-olds debate the existence of the Higgs boson particle and deconstruct Finnegans Wake. As DEET-coated children play Frisbee to observe laminar flow, adults take turns making beer runs into the dim, quasi-subterranean bar.
