The Westin hotel is close to where I live and my wife and I go here often. Were married at The Westin as well and Rick's also provided the catering for our wedding. Although no one knew that, the food was a hit as we knew it would be.
I'd say Rick's is best for breakfast or brunch. We typically order off the menu vs the breakfast buffet although we've had the buffet and it's fine. I've found the service to be best for breakfast and lunch and not so much for dinner.
Dinner service has honestly disappointed us and it's not a one time thing. I'm not sure why it would be different but the level of service and attention for dinner is close to awful. The food is very good across the board and reasonably priced. Great atmosphere and semi view as well.
