Coffee snob checking in here. We home roast our own coffee at home from green coffee beans. Freshly grind the beans prior to brewing with a Barista Virtuoso grinder. We don't have an expresso machine, but we do brew our coffee in a Brikka pot.
So yes, coffee around the DLR is quite horrid compared to a home roast. Here are the two options we have done:
Lion's preground coffee, steeped in an Aeropress coffee maker. Use the hot water from the coffee maker in a hotel. It makes a very good cup, except you go through a lot of beans.
This is almost sacriledge to say the next option. Buy the Starbucks Via packaages, they actually aren't too bad. And you won't have to walk all over creation in an attempt to find a starbucks.
