Went to Casa Mono last night. Got there early for a 7:30 reservation, and they were very good at parking me in the bar next door until the table and my group were ready. Food was fantastic, especially the sweetbreads -- we ended up ordering them three times. (Total for sweetbreads alone: $48, plus tax and tip. Ouch!) As others have also said, the lamb shank is amazing, and we also had a couple of orders of the fideos -- a small clam pasta dish. We certainly had no problem ordering sequentially rather than all at once at the beginning. We went for $65-70 wines which were perfectly good but did not quite rise to their price point. But maybe I'm just not a Spanish-wine kind of person. Total for 3-4 people came to $478 before tip: I can definitely think of a lot of other restaurants where we could eat and drink more and better for that kind of money. (There were 3 people at any one time; one person left halfway through to be replaced by another person.) We weren't rushed at all, and left more than four hours after we arrived. Service was OK. Upshot? A happy, bustling, great vibe, with excellent food -- definitely go there if you're not paying. Wasn't too noisy or too cramped for me, although it was a Monday night.
