I'll be in London for a days beginning June 13. Will have at least two and possibly three days of free time. Plan to bring my Skerton grinder and Melitta cone for the daily cup of morning drip in the hotel room but will appreciate any and all suggestions for good espresso and coffee to be sampled on my travels. I know Square Mieleis a must-visit but who or where else?
Will be staying in the Maida Vale neighborhood near St. John's Wood but don't mind a long tube ride for a good drink. Tips on good/under-the-radar/ethnic/reasonably affordable dining will also be appreciated.
