YOU MUST EAT HERE. they basically offer 4 things:
Sandwiches - a must
Salads - choose your own ingredients and lovely dressings
Juices - delicious drinks
Baked goods and Spreads - hummus, muffins, etc.
If you are in Kensington, you have to eat here. they are related to Fressen, but are the complete opposite. Great atmosphere, much cheaper and the food is to die for.
