As a true argentine I love meat! If I have to recommend a restaurant in Paris, where you can only eat meet, is "Le Relais, de l"Entrecôte"!!! I love this place, and the best part, you do not have to worry about what you are going to eat!
And... you can keep eating and eating..... they will come and refill your plate as you finish...
They have only one menu:
- a lovely salad for appetizer
- exquisite meat with or without a secret sauce and french fries ;-)
- dessert is your choice if you make it!!!
