Annapoorna chain of hotels are very famous for veg foods in goimbatore, like what hotel saravana bhavan to chennai! Annapoorna saambar is one, which everyone likes! We had lunch there sometime back, not many people know that in first floor, near the ac hall, there is one kaveri hall, where special lunch is served with chapathi and all, not crowded!
You can try here once! I feel they are doing service to the food industry!
