Tell me where I can go in Colombo to see the sights??

Port Sity.

We walked around the Cinnamon Garden area - very beautiful, visited Viharamahadevi Park and the Jeffrey Bawa Museum - you need to register in advance, but besides the Rolls Royces, the museum didn't impress much. We went to the One Galle Face mall and to the cinema, walked around the area of the Fort where the Dutch Hospital is located, there are various cafes. A year ago, we were taken on a city tour from the hotel - we saw the Tulip Tower and visited the Gangarama Maha Vihara temple - they made a thread for the wrist there. We were at the national museum, an acquaintance praised the Pettah market for street food, and we visited the Museum of Modern Art. In the evening, you can go to the rooftop bar of a nice hotel, where there's a cool view of the ocean and the city. We stayed at the Granbell hotel, the bar in the evening is very beautiful there.
