In years of coming to SF I've never dined at Postrio until tonight when proximity and hope of carpaccio settled me there with expectation of dining at the bar. Question about their pinot by the glass met with 'pinot noir is a lighter wine....'. Request to dine met with hesitation and well, I will have to ask....' as it turned out the answer was indeed the full menu would NOT be served at the bar, but accommodated in the restaurant, I accepted the first shadowy one-top I was offered, which felt so odd I couldn't decide if I liked it or not, then decided not, requested to be moved, and immediately felt better. Ordered three courses from appetizer menu: steak tartare, lobster salad (a special) and crab cake. The lobster salad was a great disappointment, bathed in a syrupy orangey dressing and adorned with mounds of shaved carrot or sweet potato (couldn't touch it so cant be certain). Crab cake was like shreddy backfin rather than clumps, and deep fried. The tartare, however, was delightful. Great chunks and quail egg and croutons.
For a hotel restaurant and one that has a fairly sizeable bar I must say I was surprised at how little they cared about a solo diner. Lots of bustle but no one save my very occasional waiter, who to be fair seemed also to be serving tables clear across the room, ever stopped to refill a glass, clear a plate or inquire about general well being, though there were many opportunities. Not having been before I can't say whether this is typical, but I have now filed Postrio away for takeaway tartare.
