Looking for a decent meal in Quseir is a frustrating process. There are a number of very promising locations, but the best places to eat are in the hotels. Of these, Seagull's at the Mövenpick is probably the top choice. On the main street there is a pair of tourist-oriented fish restaurants, the Admiral and the Citadel. If you opt for one of these, check that the fish is fresh (you'll choose it from the cooler in the front) and bargain on the price.
