Nice thing about Safeco is you can watch the game from the concourse as you're walking around to get food and drinks so you don't miss anything.
I'll often get cheapest CF rickets and then watch a few innings from different points in the ballpark. Over the bullpens, behind home plate, etc.
Edit: there's also a beer garden area behind left/center field called The 'Pen (next to bullpen, duh). There's also a beer patio above the mechanical scoreboard in near 3rd base line in left field. Cool to watch the dude switch out the metal plates to update runs/hits/etc.
