Hi Brother, there are plenty of hotels around Railway Station in Coimbatore and the best veg restaurants like Annapoorna, RHR are also available in walkable distance from Railway Station. If you are planing for like more than 2-3 days, I recommend you to take hotels those are atleast like 3 stars, near station or Gandhipuram area of Coimbatore (has good bus access too from Railway Station). For a single day visit , you can also take Retire room at CBE which is okayish..
