I was resistant to have dinner at Flour + Water because I've been often disappointed by the pizza in SF and I usually avoid places where there's a wait. We arrived just after six and there was no wait. So far so good. Dug into three of the antipasti: tuna conserva, lamb's tongue and headcheese. The tuna conserva was well balanced. Crunchy thinly sliced celery and lightly cooked tuna which was good though not as complex as the similar dish at SPQR. The lamb's tongue was the standout of the night. Tender well seasoned tongue with rich egg yolk over it and a bit of crunch from the greens -- nice. We had a similar lamb's tongue dish at Babbo and loved it. This one was as good, it makes me wonder why there's not more lamb's tongue on menus around the city. The headcheese was fine, yay for thinly sliced fried pig's ear, but ultimately a muddle of meaty flavors that was forgettable.
Margherita pizza. A very nice neopolitan style thin crust with the ends showing off a stiff exterior and tender interior and a slight sogginess in the center. The moisture in the center was not from the dough, but from the excellent fresh tomato sauce that was on the wet side. The tenderness of the crust reminded me of the crust at Luzzo's, though missing a blistered crisp exterior. I prefer the crisper style, but wouldn't hesitate order this one again.
Next course was two pastas one fat ribbon herb pasta, the other was a tagliarini with lobster mushrooms. Both of the pasta noodles themselves were well made. The preparations were simple, one with a pork cheek sugo which had a slight sweetness counterbalancing the herbed pasta and the brocolli. The tagliarini was a bit less al dente than I like but that's typical of fresh pasta. The consensus at our table was that the dishes were somewhat oversalted. A minor distraction because the preparations were flavorful enough that we could still taste herb in the pasta, deep earthiness of mushrooms, and a hint of citrus.
Ended with the chocolate budino which was fine, if fairly straightforward. I'd order it again, but it's actually just two notes, rich chocolate with a hit of salt.
My friend commented that the server was rather brusque, the diner sitting next to us leaned over and agreed. Perhaps she was just a little overwhelmed by the wait that was forming, so I understand. Despite the lukewarm service, the food and prices were friendly enough to make it a good neighborhood spot. Next time try more of the antipasti.
