now this is me being picky, but on my last stay in your nice capitol which one was elated and will be going back at chrimbo, even the hotel bar had the affronted the coffee. Surely you lot realize the coffee doesn't taste the same from the first grinding or forgive one for saying so but our most obsolete in memory to the taste factor difference between first heating and warmed up coffee, ugh. comments ta.
