Abuelo's Mexican Restaurant

They are one of the best Mexican restaurant in Knoxville

I asked and they do.

It opened July 4th 2006.

Yes

Yes, they have signs on their door, took down the Knoxville Facebook page, removed the location from their website. It was a total unannounced closure. I had just eaten there days before and got the weirdest service. See my review.

Staff wears mask. They do not seat to full capacity. Customers required to wear mask to and from their seating.

I am sure they do
