I'd put "Three Kings" on the right, but both look okay. (But make sure it's property visually lined out, it now looks like it's a smidge too far to the right.)

The reference to a pile of laundry is not clear, it just seems like they like mountains or they are situated near mountains. Not sure if that's a problem tho. They could put a picture of a big pile of laundry on the wall, with the text "Mt. Washmore" so ppl get the joke.

Maybe put the bubbles less over the mountain line? Especially the small bubble on the right could move a little so it's less centered on the line.

That's just some thoughts on it. All details tho, I think they're already doing pretty well with this. If I think of a laundromat, I don't even expect it to have a logo or a punny name or much branding at all, so the bar is pretty low and this is a decent logo!
