Southbeach is a great escape
very walkable, safe.. no muggers. However it also is full of sketchy international guys just creepin around and being douchy. The nightlife is very douchey as well, it caters to the Very Hot. If you are smokin hot you will fit in.
Insider Tip:Get ready to spend lots of $$$ because it aint cheap here. The place caters to big ballers. Cover charges for guys in the clubs is very high.. $40 some places, and very strict dress code for guys.
