I have been to Nilgiris many many many times over the years and in fact we used the catering on site service for our wedding ( dancing night before wedding). Service, food quality, cleanliness and the ambience have gone down quite a hit in last approx 2 years.
Cleanliness is a big turn off for me and I have been seriously considering not returning in future. Food quality is much better at Guru Luxshmi than Nilgiris.
