I've heard good things about Farhat but I never went. Today I tried a merguez sandwich for 3.50$tax incl. at le marche d'alimentation le Mediterranean and it was quite good. The bread was your typical commercial french roll, nothing special there. The merguez had good flavor, were quite juicy, and the casing seemed kinda crispy/fresh (I didn't ask whether it was a natural casing or not). The condiments available are tomato sauce, harissa, pickled eggplants?, tomato, olives and lettuce.
I was wondering how do places like Farhat and that place next to Sindibad compare
