We can actually do bar crawls
LA proper's not known for being specifically proud of its booze, but Pasadena? We're where the first LA-area microbrewery, Craftsman, started, and Old Town is a dream for bar crawlers: you can hit some of LA's best whiskey bars (Blind Donkey), cocktail bars (1886), and beer bars (Stone! Congregation!) in the same night... oh, and Punch, LA's only, uh, punch bar, too.
People actually can -- and do -- use public transit
The Gold Line comes in handy. Hop on the Metro and land in Old Town via two stops, Memorial Park or the Del Mar station. BTW, that last one drops you off at the Stone Brewing door, soooo maybe just use that one?
