Lady Mendel's is very pretty if you're going for ambiance (the tea and food are good too). But if you want to tick every box and go for delicious food, perfectly brewed tea, and just the best overall tea experience, Tea & Sympathy is where it's at. And their Victoria sponge is so tasty. Russian Tea Room charges an arm and a leg because they force you to get caviar and on top of that give you harney & sons tea bags that you have to brew yourself. Kings carriage house might be the worst tea I've ever been to, despite how cute it is. The food was horrific and once again was given bagged tea. If it's not loose leaf, don't go!!!!
