Going to San Fran in June; what should I check out?

So I am taking my first vacation ever, and heading West to San Francisco this June (June 22nd to 24th to be exact). I am planning on checking out 2 games between the Giants and Twins (since I live in MN and am a Twins fan), and I've got a couple other ideas for things I need to see (The Metreon, Pier 39, The Ripley's Believe it or Not Museum, In and Out Burger). My question you fine folks is, are there any, lesser known cool sites to see in the City by the Bay? I am dead set on trying In and Out, but are there any other local delicacies for someone such as myself?

Alcatraz obviously. 
LucasArts, although all you can see is a statue of Yoda. 
Can't remember what else I saw when I went.

It kind of depends on what you're into and how much you're willing to spend.  In terms of obvious stuff, definitely check out Chinatown, maybe Coit Tower and Lombard Street.  If you're already going to Pier 39 you might as well see Fisherman's Wharf and Ghiradelli Square.  Haight-Ashbury is a spectacle, but I don't really like it. 
 
I really enjoy Jack in the Box, but I don't know if they have those in MN.
 
If you're into anime or manga check out Japantown Mall.  Golden Gate park is pretty, if you want something low-key.  Wear good shoes and dress in layers, and take cash for the busses.

Starfleet Academy has tours on weekdays.

Take a package of new things they haven't gotten in the mailbag videos and take it to the Whiskey Media offices?

Has anyone been to TILT inside the Metreon? I hear that place is a complete crap hole now.

The Whiskey Media offices.

"  Ghiradelli Square. "

i think if you can take a trip to LA for like the day. it would be pretty fun stuff there also.

Head to El Farolito in the Mission for an amazing burrito.
 
If you're over 21 go to el rosamunde in lower haight for a sausage and take it next door to Toronado, the best place for beer in the city.

The Metreon sure ain't what it used to be. It's still neat to check out. Also I second everyone saying Chinatown, and the Academy of Sciences. Try and hit up a planetarium show, if you're into that sort o thing. "

I'm also going to SF in June, only I'm traveling from Australia to get there. If I wanna see a basketball or baseball game over there, will I have to buy tickets in advance? Or can I just buy one on the day? I'd be stoked to see the Lakers play, but whenever I see them on TV the stadium is always full.

The mall's huge, you can spend all day bsing in the Bay Area, and the massage places in Chinatown really are a cover for prostitution. Not kidding. About 150 gets you full penetration, not just a handy.

Go to Tony's Pizza Napoletana on Stockton. they have this deep fried Pizza Margherita. It's killer. make sure to check out chinatown, the exploratorium is cool if you have kids. Uhh, Alcatraz is always fun... And the comic book museum is also pretty cool if you like comics. It's right by SFMOMA. You could also kinda try to find IGN headquarters and stuff. I'd say find Giantbomb HQ but htat would be quite the drive.

Go to San Francisco State University's arcade "Rack n Cue." They have Super Street Fighter IV Arcade Edition and The King of Fighters XIII. "

Huh. I go to SFSU and I didn't even know that. "

I have no desire to stop by the Giant Bomb offices. I don't want to cross the line into weird territory. 
 
As of right now, I plan on visiting the Exploratorium, Alcatraz, while in the area Pier 39 (yeah I know, touristry), In and Out for lunch, and then AT&T Park. That's just on Wednesday. Anyone know of a good breakfast place?

hopefully you'll be lucky enough to see the hoe truck being driven around the city.
 
  

Anyone know of some good local eats? Yelp tells me I should go to Little Star Pizza, and I know for sure In-N-Out will be a stop as well.
