I'm still a relative newcomer to LA - so haven't tried some of the favorites. The tasting menu at SONA was mouthwatering (401 N La Cienega Blvd West Hollywood) the setting zen like and elegant, customers seem more dressed up then the usual super casual attire even at fine places - the staff is refined (something lacking at many LA restaurants). It would be my first pick - and then I'd return to their Patisserie BOULE (across the street) the next day for a sweet treat. Both Providence and Ortolan are serene and Ortolan is more romantic - but I think the food is brighter and livelier, more fish-centric and at Providence. Wouldn't consider Table 8 romantic - a tinge loud and the food is good but not in the same league as Sona. Might as well go to Osteria (loud and lively and fun and richly flavored) and one of the impossible reservations to get right now. Belvedere at Pennisula Hotel is more refined and elegant then outright romantic - maybe it was the number of business dinners occuring at surrounding tables (and...every dish was heavily salted!!!). Bastide just reopened and word is the tasting menu is stellar - not sure if it's romantic -- I haven't been yet - perhaps someone else will comment. Enjoy your trip to LA.
