I have been to many Waffle Houses before, but this one is gross. I had to get up and leave due to general lack of cleanliness. We sat down at a ""just cleaned"" table which still had a big smudge of syrup or jam on it, then we grabbed our menus which also had finger-smudged gunk all over them. I ordered an ice tea and the aftertaste of it was gross... it had been over-brewed. It was incredibly cold in there as well, which was totally unnecessary considering the temperature outside was in the 70's. Yet they had the AC on full blast and I was uncomfortably chilly. The final straw for me was when I saw a small group of flies buzzing around next to the window near my table... at first I didn't think anything of it; I thought they were outside the window. But then I noticed they were all actually inside, and if I can see that many flies right at my table, there must be quite a few roaming freely inside the restaurant. Overall lack of cleanliness made us get up and leave. I shall not come back to this particular Waffle House.
Output:
NEGATIVE
