I have visited Cafe du Livre a number of times. It is a cosy, warm and intimate lounge bar stuck in the heart of Gueliz, the new-town. The owners Liz and Younnes have a very personable and friendly approach, and always make you feel very welcome. Alcohol is served (happy hour between 7 and 9pm) and wine bottles can be purchased to take away. The food is made up of an array of dishes ranging across Moroccan, Italian, Thai and US cuisine and it's worth checking the specials for an unexpected curry or other ethic dish. A separate area of the bar is dedicated to a substantial library (hence the venue's name), with space to sit comfortably and read, with most English titles hard to retrieve elsewhere in Marrakech.
Often there will be live music, and a friendly, jolly atmosphere. Liz goes through the trouble every week of completing thorough research in all areas in preparing for the Monday night quiz, that will prove a challenge for most.
It must be noted that Cafe du Livre is generally known as one of the major social meeting points for the English-speaking expat community in Marrakech. Those new to the city and looking to meet people, or even those who are here for just a few days and wanting to have a chat and get some useful information, could consider Cafe du Livre.
