Jemaa-el-Fna stalls are a great place to eat and there are loads of them to choose from.  They offer a wide variety of local food prepared fresh on the spot for as little as 2/3 euro (depending on what/how much you eat).  They start serving at dusk until around 2 a.m. and, as the food is on display, one can take the time to look around (expect a little harassment but just ignore it). For those who enjoy fish nr. 98 is a must and they even have a moroccan version of  "fish & chips".  Some would prefer to avoid raw vegetables (but there are plenty of deliciously cooked ones) and bottles should be opened in front of you.
