Yes, it is a chain but I very much enjoy it!
I have been to the McCormick & Schmick's Seafood Restaurant inside the Park Plaza hotel many times. I have also made a few visits to their Faneuil Hall location. They make up their menu twice a day, for lunch and dinner, based on what is fresh. The menu is mainly seafood though there are steak and poultry options as well. Lunch is a good value as the prices are usually half that of dinner, and meals are still fairly large.
Tonight I stopped in for a quick dinner and sat at the bar. I chose the Red Tilapia with a cashew crust and Jamaican hot rum butter sauce ($19). This comes with rice pilaf and mixed veggies. I received a good sized piece of fish, moist and flaky. The crust and sauce is excellent, a sweet taste with crunchy nuts. They use this crust and sauce on other fishes as well, such as catfish. I have had it before and have always enjoyed it.
Their fish is always fresh and delicious. I don't recall ever having a bad meal here. Give it a try at lunch when it is inexpensive. And I bet you return for dinner!
