Porvoo isn't that big a place, especially on the off-season when it's colder. But it's a nice day…read moretrip from Helsinki, with a cute neighborhood and chapel. Walking around the town doesn't take too long (2 hours), so it's nice to have a place to kill some time/get out of the cold/heat, and grab some nice coffee/drink and kick up your legs. This GEM of a cafe/bar is right under the main overpass/road into town. The downstairs area is bustling and cozy, but the upstairs area is the really cute place so I definitely recommend everyone to go up there to check it out after you get your wine/coffee/etc.
It's got a great wooden decor inside, a really romantic vibe, but I could see it getting my happening at night/on the weekend nights. There were seriously like 3 couples on coffee dates there. I've heard the coffee here is great but didn't have any, just had a nice glass of red wine. One thing I'd say is that it gets really crowded/long line when a big crowd walks in, they should probably figure out an easier way to serve people.
BTW, this place was listed in Lonely Planet, and normally I don't love all their suggestions but this place is definitely worthy, especially for a smaller town like this.
