If you like meat, roar, well-done or else, I can highly recommand you "Le Relais de l'Entrecôte". They have only one dish: twice a beef entrecôte with fries and homemade sauce. It's about 40.- per person but you wouldn't regret afterwards.
It is near the main bus stop "Rive" (buses 2,6,7,10 and tram 12). You don't need any reservation. Actually they don't take any. It is so famous they always know someone is going to show up ;) over 3 years ago
