Right beside Trivandrum's main bus stand, this branch of the famous Indian Coffee House serves its strong coffee and wallet-friendly snacks (biryanis, omelettes, masala dosa; savoury crepe stuffed with spiced potatoes) in a red-brick tower that looks like a cross between a lighthouse and a pigeon coop, and has a spiralling interior lined with concrete benches and tables.
You have to admire the hard-working waiters.
