Bars: Always open till 2. The fun thing though (or bad, depending on your POV), is that the undergrad green st. bars allow in 19+, while 21+ get bracelets to drink. This makes for great opportunities to drop the law bomb: "My buddy here is #1 in the law school class..." I've seen this work to marvelous effect.
How diverse would you say the law school is? ie. Racially, geographically, socially...ect.
