19 RMB for a double espresso as delicious as what you describe is a steal. I'm gonna go all the way out there just try it.
The best espresso I ever had was at Maan in Lido a looooong time ago. It's not the same anymore.
The only coffee I like from Starbucks (no, it's not all bad) is the Kenya roast. You have to trust me on this. Skip the Breakfast Blend and the Guatemala and the Italian and French and Verona and whatever else is on display and go straight for the Kenya and ask them to grind it up for you.
It literally smells like buttered toast.
