NITE LITE 1926 Second Ave, 443-0899 I've been to a couple good dive bars in this city, but it's hard to find ones that really fit the bill--tacky, unintelligible décor, old droll bartenders, and drinks so stiff that two will set you back half your brain cells. NITE LITE fits those checklist items perfectly--it's always some kind of Christmas/holiday/something in there. Plus, two of those small water-glass-sized cocktails and the jukebox is finally entertaining. Females may find themselves the objects of much "sports bar dude" affection on certain nights, but overall the diversity of the crowd only adds to the place. JENNIFER MAERZ
