Is this place open on Sunday? I don't see a weekly hours chart anywhere...

Yes it is it just closes at like 8

Yes

I just googled it and it said they're open from 10am-7pm Sunday's at the Valley Michaels. I believe they all have the same hours though.

I think they are open 10am - 9pm on Saturday.

Yes it is. I think they open till 9:00 pm
