Serious drinking, in and of itself, is a descent into darkness. It’s fitting, then, that to reach the dimly lit College Inn Pub on University Way Northeast, aka the Ave, one must walk down a dozen or so stairs to find a subterranean collection of faintly British-feeling rooms where it seems the Hunchback of Notre Dame might drink pints of grog from a wooden mug. In any other college town, the College Inn Pub would be a perennial cash cow.
