8550 Westheimer, what are the building?

Posted about this a month or two ago. I'm just genuinely curious what it could be!

Initially thought it could have been a Dutch Bros Coffee but now that it's more built out, doesn't seem to be consistent with the branding. it's placed in a area where parking or some sort of drive through would be a really tight fit, however, there seems to be two car bays built into the building, with a small enclosed section next to if?

Could be a Take 5 style service station? Absolutely not important, I just like to speculate. Anyone have any thoughts? 😁
