Thanks to this board, I discovered Myth. It's as good as everyone has raved about it. Had the cauliflower soup, Prosciutto Di Parma Pizza with Figs, seared scallops, Garganelli Pasta with Foie Gras Cream, and Risotto with Chanterelles. Forgot what we ordered for dessert. The total came to around $1xx (food+wine+tips). All in all, a good value.
Tried the 9 course tasting menu at the Ritz Carlton. It was very satisfying. Impeccable service. But, in retrospect, should have just tried the 3 course meal. A 9-course tasting menu is a bit too much food for one evening.
Had very good brunch at the Canteen (next door to the Commodore Hotel). It was worth the wait for Sunday brunch. Poor waitress, she has to do the whole dining room herself and yet never loses her cool. Very friendly and professional.
Also went to Ton Kiang, it's still the same as our previous visits. The salt baked chicken is very good. Didn't bother with the dim-sum.
Other worth mentioning:
Sunflower vietnamese restaurant on Valencia and 16th is decent, very large serving and interesting wait staff.
Shalimar on Polk (not the tenderloin location) does not have as good food as the tenderloin location. Then again, it may be just my perception.
Little Szechuan in San Mateo is good and cheap though it's quite spicy. I eat very spicy food and it was even spicy for my taste.
In-n-out (Fisherman Wharf) was not as good as other in-n-out that I had tried.
Japan town japanese food is NOT worth trying as well as Niko Niko on the Union Sq. The ramen had some funny taste. It's not bad but I wouldn't call it decent. Wanted to try Santa Ramen in San Mateo, but they were closed we got there, hence we tried the Little Szechuan.
Again, thanks for the tips on SF dining.
