At TuckShop, you get what you pay for.
This little vegetarian (with vegan foods being indicated in the menu) place with very few tables enables you to have a homemade food fix for probably almost the same value (adding on the time and effort) it would take you to make it at home.
Menus of salads (including 'salads' of brown rice, red beans, and avocado) and sandwiches for less than 10€, which is surprising in Paris, and homemade juices. That being said, if you're looking for cutting edge new experimental food, this is not the place to go. The food can lack a little flavour sometimes, but the quality is great.
Although the place has a nice cosy environment with lovely magazines and cook books for you to read, instead of sitting inside (there is no toilet!) grab it to go and sit by the canal.Pros: Affordable, homemade feel, great produce, Sweet service, environment and location.
Cons: No toilet. , Food could lack flavour
