I grew up with Red Lobster being the epitome of seafood dining. We won't even get into the Joker's Wild crab leg buffet - my counselor advises against it.
The thing about M&S is that they fly their food in fresh twice a day, and print a new menu twice a day to reflect their freshest selection. Everything I've ever had has been delicious and I've sampled their bisques (creamy and rich), pasta dishes, filets - just about everything. The quality is consistent and I've never once been disappointed.
