Mae is in the 9th district of Paris and is very nice and cozy. You can not only eat but you can also organize events and talks throughout the week. At the top there's a small exhibition of fair trade products and you can buy juices, chocolates and handicrafts (they're quite expensive). The food is good, we had fish soup and shrimp soup in coconut milk with basmati rice. There's a wide selection of dishes from around the world, perhaps more Asian and Indian and dishes are 15 euros/person with a dessert (it seemed a bit small but I left full). They serve a good selection of teas and coffees. The restaurant is on 2 floors in an old house with hardwood floors, it's a quiet place with lounge music.
I went to Indiana Cafe in Gambetta Square not knowing it was part of a restaurant chain. I found myself in a comfortable place and the food was great quality for a reasonable price (a huge mixed salad for 10 euros). It was decorated in warm colors (orange and red) in a "tex-mex" style. I sat on the deck one day to enjoy a coffee in the cold winter, thanks to an external heating system (not very ecological but nice for smokers who have to stay outside!) Who said that franchises were always bad? :)
