I go to The Prado for every special occassion with my husband and family. We absolutely love it. I have always gotten amazing service, even when they were packed. My husband and I are going this Valentines Day (crazy right), and expect it to be superb.
As to the person below me, this is a gormet restaurant, its a presentation of food; if you were expecting a heap on your plate, you should have gone to IHOP. Restaurants like The Prado, are showing off how well they present food; how it looks excellent, just like it tastes. Since it is a presentation, it is not demonstrating how much food they can slop on your plate. It is an art. Not to mention, you are getting some of the best cuts of meat, the freshest salads, the most delectible desserts in the city. So enjoy what you eat. Savor the taste, and the beauty of the presentation.
And if you conversate with the waiters, and waitresses, they will feel more inclined to give you everything you need to be comfortable. If you respect them, they will respect you. Its the same as any restaurant, or place of business.
I have gone to The Prado, say more than 50 times in my life, and each time is a memorable one.
