There is a local upmarket curry house near me that is quite good and has been around for nearly 5 years winning plenty of local awards for food and service, but on TripAdvisor about 1/5 of the reviews refer to a steak house that was at the same address before this curry house opened. They did not get good reviews and didn't pass health inspections. Even though the curry house changed the owner, name, management, waiting staff, chefs, food sourcing, decor, and menu the reviews are still tied to the address. Fortunately their newer reviews are so glowing that they still get over 4 stars average and their front window is covered in plaques of their awards and their most recent 5/5 health inspection (in the UK its quite common for restaurants to flaunt their 4/5 or 5/5 health report on their front door as advertising - there is no legal requirement to show it except in the city of Hull where now almost every restaurant now has at least 4/5 rating as a consequence given the death sentence that a something below 3/5 represents).
