<human>: My wife and I are headed to San Francisco from April 16th to the 20th.

She is a "foodie" who should have gone into some sort of culinary profession, while I am a "techie" that loves to drink and merely follows her foodie desires.

We have about 2k in spending cash for the week. Hotel and Airfare are already taken care of.
Staying in Union square somewhere. We will mostly be walking, but take a cab if we need to get to someplace that needs to be seen.

Can anyone that lives there or who has travelled there during the mentioned times of the month list a few things for us to do?
Bars, dives, restaurants. Tours to take. Anything is open.
Even a really good guidebook that I could read in the room but not take with us while we are out.

Right now, we plan on an Alcatraz tour. A Golden Gate boat tour. Eating at someplace on the bay a few times. But that is it!

Any help will be appreciated!

Provide a brief overview of the text.
