I say Wolfgang Puck's. Portabello Yacht Club has really gone down hill over the past few years. It has always been really expensive, but the food and service were top notch before too. The menu is pretty diverse offering meat, shrimp, fish, chicken and pork as well as a few different pasta dishes.
However, WP Cafe has something to please everyone. The menu is large and offers great pizza, pastas, big salads, large selection of appetizers, sushi, ribs, chicken and fish entrees. It is a little more reasonably priced for what you are getting. We have always had great food and service here.
