Not all of the stores will open Wednesday. There will be staggered openings and everyone should be back by June 2.
Alexandra LaRonge owns Slime World which specializes in slime, she's had to rearrange her store to allow for new recommendations from the health department.

Other business owners have been there over the past couple of days preparing for the opening.
Felipe Hernandez of Taqueria Mi Mezcal is hopeful to have customers come Wednesday.

"A lot of my client's friends and coworkers start texting me since 2 o'clock this afternoon but we haven't heard yet anything official from the county or the city," says the owner Blanca Ambriz.
Solano County officials say that despite Governor Newsom giving hair salons and barbershops the green light, they are still working on updating the health order and don't have an opening date yet.
The owner of the Village Clip Shop in Vacaville says it's confusing. He's had to cross out the opening date on this sign several times.
No uncertainty at the mall though, which may just be the coolest spot in a town that has hit 100-degree weather in recent days.
"It feels good now doesn't it? Finally, cause we did have it off for a while so it is nice and cool in here now as we have merchants all getting ready."
