EArchitect: Great atmosphere & views of London's South Bank on the River Thames from the 12th floor!
Cenker: If you like Thai food, you must visit one of Busaba Eathai's in London. "Thai calamari" is to die for!
Cenker: Small cafe, you might wait but it worths. One of the best coffee of London.
Oula: One of the best coffee experiences one can have in London :)
EArchitect: Great location on the South Bank right on the river's edge with views of St. Pauls and close to Blackfriars Station. During the summer, it's a great place to chill, drink and watch the sunset (not to eat... food is so so).
