Reservations are a must, as are deep pockets. There is definitely nothing fancy about Lawry's. Just big hunks of the best prime rib around - slow roasted and carved at your table. All cuts come with a portion of their famous spinning salad. Mini lobster tails are available to complement the beef.
Prices here are very reasonable, especially compared to the major steakhouses in town.
You could easily go here on your own dime. It's just a notch below the top steak places in town, but Magnum's makes for an interesting change of pace nevertheless. The lineup of beef is solid, as is the rest of the menu. Beware of the entertainment, which can be outright terrible. Also beware of the obscenely high prices.
