Jostle your way through the box office and concession lines, and find a seat — if you arrive early enough — somewhere where you won't get whiplash. Try to ignore the crying baby, the ringing cellphone, the oblivious conversationalists behind you, the pounding noise from the action movie in the adjacent theater. Wait a minute — this is supposed to be best night at the movies, not typical night at the multiplex. Let's start over.Amble through Bayfront Park to Movies by the Bay, buy your ticket at the "box office" (it's actually a trailer; $9 for adults, $6 for children age five and up, $6 for seniors), grab a beach chair (there are 209 on site), and enjoy the bay breeze and glistening downtown backdrop. Movies by the Bay gets first-run films that cater to mass audiences (300) and families (Shrek the Third), but owners Bill and Susan Hertig also have the good taste to screen more refined offerings like Pan's Labyrinth and The Queen. The "concession stand" (also a trailer) offers the usual salty-sugary fare. They'll even give you something for free, something those multiplexes wouldn't dream of: mosquito spray.
