Well, I do not have a favorite low carb friendly restaurant per se, but my favorite dishes when out (I eat out a lot):
1. Japanese- sashimi! Especially salmon
2. Steak/seafood- shrimp cocktail (no sauce) and steamed clams/mussels in wine or butter
3. Diner- omelette (with cheeeese and mushrooms)
4. Mexican- ceviche de pescado and a salad with shrimp/scallops or shrimp faghitas withut the bread, rice and beans (I just use a fork to eat the lettuce, tomato, salasa, guacomole, sour cream, cheese, shrimp, grilled peppers/onions...)
5. Greek- salad, tzatiki served with cucumber slices, olive plate, flaming cheese, baba gnouish sevred with cucumbers....
6. Crab places are the BEST
Ooh...love the salad bar at ruby tuesdays
