It seem an Espresso is 5 EUR and a Tea will set you back 8 EUR.
But it is Cafe de Paris, after all, so you should expect to pay that.
Agree about that, it is extremely boring, everybody that lives there is︂ sad and alone - as evident by the fact that everybody in the street is︃ walking alone with a dog.
If you like living in a place with 90% rich︄ widows/divorced ladies that can't even move their faces due to so many plastic surgeries, then︅ Monaco is the place for you.
If you like actually nice friendly people and interacting︆ with people that are not rich assholes, then you will suffer every minute there.
The only reason it still survives is because people want to be able to say "I︇ live in Monaco" as if anybody is impressed by it. Just take the 8k/month rent︈ you would pay and buy a nice watch with it, you will make the same︉ impression without having to live in a sad 50m2 jail. Every single person I know︊ that lives there is flying away every 2 weeks as it just becomes unbearable.
P.S. It's great for celebrities as the safety is really paramount, and papparazzi is illegal.
