If you have read my reviews before, been in the business for over 30+ years! - Had a smell of a GREASE TRAP when I walked in!!! My question is looking at other reviews, were they having a TRAP BUILD-UP, or something else!!!! WELL GUESS WHAT - If I was an inspector for NSF, I bet they had OIL THAT WAS BLACK and THAT IS SAD!!! If you have proper training, you can save $$$$$ by FILTERING TWICE A DAY and to BOIL OUT YOUR FRYERS EVERY WEEK!!!! The server was told, and NOTHING DONE!!! Will not be back! PLEASE NOTE: If the 5 & Diner Chain is still the way I remember, all locations are franchised, so please do not think every one is this way!
