Another paradise for tea lovers (including my mother-in-law) is Tea Stand located on the backstreet of Omotesando. Crystal chandeliers contrasting with suspended colorful herbs create a bit of a whimsical atmosphere.
Particularly impressive is their selection of French toasts as well as amazing Earl Grey Tea.
They have packaged teas for sale as well. I also tried their savory courses – Caesars Salad which was quite tasty and pho soup, which significantly lacked in flavor.
