Anyone who rates this Spago less than 5 Stars clearly did not have the tasting menu. We made reservations early for a Thursday night and asked the maitre d if they could do a tasting menu for a vegetarian and a non-vegetarian at the same time. He laughed and said it wouldn't be a problem if the chef was in a good mood.
When we arrived, I asked our server if the chef was in a good mood and he responded "Yes, and we love vegetarians!" In fact, he told me that they can accomodate people of all allergies, sensitivities and preferences including vegan or gluten free.
The reason Stefan D did not get a written tasting menu is because the chef makes it up as he goes along (which we learned from the chef two years ago when we came to the same location for the tasting menu and he came out to visit with us toward the end of our meal). Although each course is not a great deal of food, you will be absolutely stuffed by the end. The most spectacular part of the meal for me was these enormous ice teardrops that were hollow and contained two spoons of different delicious dishes. (My nonvegetarian husband asked me three times to tell him what the house made lychee beads were he loved them so much).
As expected, most of the dishes for me were vegetarian versions of the meat dishes - I got a portobello burger instead of Kobe beef, but I'm not a big fan of portobello normally and I LOVED it.
The service was also excellent. I cannot say enough wonderful things about this Spago. It was an experience you don't want to miss. One word of caution, if you get the wine pairings with the tasting menu, make sure you are not driving afterwards.
