This place is an institution; I'm sure it's been in the same awkward, T-straddling location since the dawn of time, scrubbing the grime off soccer moms' SUVs and dads' sedans. I will say that I was impressed by the newfangled card-reader and frequent-buyer system they've got going on; Grandma was impressed by the novelty of being conveyed through a sea of scrubbing bubbles.
Pro tip: the little glass cleaner wipes they give away? Try leaving a few tucked into your front cupholder as a subtle hint that you live in, or near, Mt. Lebanon. Cheaper than a trip to pick up an OBX sticker for the rear windshield.
