Pretty sure you gotta eventually order a new batch of tacos

Typical with black bears scare them away, in this case it appears to be a problem bear that has been accustomed to humans due to people feeding it resulting in them not fearing people. For them likely walk away get help.

Scare it away or leave as it munches. It's a cub so I probably wouldn't try scaring it in case mommy is nearby but it's a black bear so you've got a good chance of keeping all your body parts.

at the very least I think you want to ease up out of there while there is still plenty of food to focus on

at some point that bear is probably going to want to try and lick some fingers if it’s still looking for food

Walk away

"Go away! Go away! Stay tuned for an all-new Ally McBeal!"

I mean while I am not going to try and fight a bear, I would like to think that I would put down the phone and distract it while my family gets away from it.

Drop a boulder on it.
