I’ve only been in Ottawa for a weekend. It was pretty cold and we had a snowstorm so the visit wasn’t in the best conditions! However, that was a great time to stay inside and to visit the Parliament Buildings were destroyed by fire in 1916. Its glorious library survived and the rest was rebuilt in distinctive neo-gothic style. In the librairy, you can admire books everywhere and beautiful woodwork. You just want to stay and read there.
For foodies, we had a great hamburger in a small Irish restaurant but I can’t remember the name. We tried Poutine and enjoy and weird huge yogurt with ice-cream. Delicious!
