Start with Coffee House Restaurant and Mainamati Museum
Use one real cafe and one real sight.
- Start at the cafe
- Move to the sight
- keep the next stops close enough to make sense
Start the day with Coffee House Restaurant at Moynamoti Super Market, Cumilla Cantonment Foot Overbridge, Cumilla, Bangladesh, then move to Mainamati Museum at Shalmanpur, Mainamati, Cumilla, Bangladesh.
That gives Comilla a route you can actually explain without falling back on generic district talk.
If you still want one extra stop, use Victoria Food Park or Cumilla New Market only if it stays on the same side of town.
