Beg to disagree under certain circumstances, my NYC friend. Since the vast majority of my research was before medical school, most of the focus during interviews was on that work rather than the piddly stuff I did during the last 4 years. It was one of the reasons many of the Univ programs said they had invited me for interview.
Caveat: my work was published, fairly extensive and some high-falutin' stuff. Undergrad "research" which might only entail being Chief cook and bottle washer is probably not highly valued. But if you have something more substantial IMHO it can be of benefit to you down the line.
