Never been to FF, but ate at Fulton's just last night and thought it was great.
We went about 8:30pm with no reservation. Had to wait about 30 min to get a table. We ordered the Portebello Fries and fish tacos for apps. Both were very good although the fish tacos had more slaw than fish. My 9 yr old son choose the Snow crab kids meal. I could not believe that he picked that, because he usually only likes fried stuff. He had the best time cracking the crab and pulling out the meat. My husband had steak and shrimp. He was happy with, and he can be picky about his steak. The only only thing that I did not think was that good was the fried fish and popcorn shrimp that my DD and I shared, but my DD liked it.
Now, it was expensive. It will probably be the most expensive meal on our trip, but we would go back without hesitation.
