All the reviews here that rave about Sotto Mare are absolutely correct. The food is excellent, the families that own and run the place treat you like their own and it is by far the best place I've eaten in San Francisco at any price. And that's the kicker - prices are quite reasonable. My $19 plate of steamed little necks piled high and wide was exquisite and my companion's $19 swordfish was the best he's ever tasted. The menu is short - and that's a plus - with simple dishes. Yes there are a couple of drawbacks - the place is small and waits can be long and they don't take reservations for two. On the other hand, the free glass of wine does help to speed things along. All in all a most satisfying experience especially the friendliness of the owner and staff.
