This is definitely a below average Wendy's although as other have mentioned, your options are limited in this area and this is probably your best bet. I have experienced long delays here in the drive through (20+ minutes with 5 cars in frort of me to start.) My order has ultimately been accurately filled though. The food is normal Wendy's fare.
The interior is fine and can get busy at lunchtime. It is not especially clean, but not egregiously dirty either. On the low end of normal. I have never felt unsafe here.
