Got Quattro? - You must have had an isolated bad experience at Portobello because if you think it's better than RFC, yikes! Portobello is outstanding and very consistent. As someone who has grown up in an Italian restaurant family for 35 years, I can assure the OP that it is outstanding - to say that it had poor food, I am wondering what your definition of good food is? There tomato sauce is pretty much out of a can, yet Portobello's is homemade. I can't imagine burgers and fries at RFC being better than authentic Italian food!
Hopefully the OP will try out a variety of restaurants and make own judgment.
Happy eating, Tiger
