Sens is located in Embarcadero Center 4, just across from the Ferry Building in the Financial District. Truly elegant food. Leans to mid-eastern and Mediterranean flavors. My experience there was all about perfectly blended flavors, exquisitely cooked food, and presentation that hit the exact right note. The portions are normal (not too big or too small) and the atmosphere is pleasant. The menu is easy to interpret, the selections are seasonally appropriate, and the wait staff knows what's what. It was not too noisy and the tables were far enough apart. Plus, they have ecru linen table clothes and napkins (without the butcher-paper-over-linen of the faux elegant movement). Price is on the high end but nothing was overpriced for what was presented. Count on me being there again as soon as I can.
Zazil is one of my favorite Mexican places to eat in San Fran. It is located in the Westfield Center on Market Street, on the fourth level near the dome. Each table is presented with tiny corn tortillas wrapped in a linen napkin, warm and tasty with three different salsas--one chared, one smokey and one green--still can't decide which I like best. If you are there with a few people, be sure and order the guacamole, made for you tableside. My favorite entree is the chili relleno which is not battered and fried but baked. Taste, presentation and service all get top grades. Atmosphere is a bit weaker but nothing to hinder your experience. I make it there for lunch at least every time I am in town.
Unicorn Pan Asian Quisine (scallops or beef with green beans) is on Pine Street, Tadich Grill (calamari steak, pork roast) on California Street and The Slanted Door (spring rolls) in the Ferry Building and Taylor's (burgers and sweet potato fries) in the Ferry Building too--these are some of the best I've found.
Breakfast will be a whole other blog.
