Morton's gets a 4 star because they are more expensive than Peter Luger's and not as good as Peter Lugers.
However, Morton's is a very good chain steakhouse. I'd suggest going with a group of people so then you can order the porterhouse for 2. It is delicious. They bring it out on a hot place and set it between the 2 people eating it. You are then each given a piping hot plate with hot butter drizzled on it. The server then puts some of the meat on your plate and rubs it around in the butter. Delicious. For the sides, I would suggest getting the creamed spinach. The asparagus isn't bad either.
I actually went there for my fraternity senior class dinner with a group of 8 guys and they gave us our own room which was really cool. You just have to put down a cover for each person which you lose if one guy doesn't show up. We all got the porterhouse for 2.
For deserts, you need to get the souffle which has to be ordered with the meal because it takes some time to make.
After multiple bottles of $60-80 wines, the total tab came out to a little more than $1000 for the table which wasn't too bad.
