You have a lot of people bitching about this Walmart, but it's Walmart and it's at 36th street and Thomas. You can't expect much.
I have been going here for several years, and the complaints I have are mostly with their lines. I am normally always waiting about 20 minutes and it can get frustrating. But, I do mostly all of my grocery shopping there because they are cheap and have a really good selection of vegetarian items.
The store is not dirty, but its not clean. This area is heavily populated with non english speaking people and you will run into them in the store.
The cashiers are normally really nice here. I have never had a complaint about a cashier.
Aside from the long lines and the area, which Walmart cant really help, I dont have any problems with this store. THey have a good selection, great prices and its about five minutes from my house so I wont complain one bit.
