Cafe Pasqual or La Boca?
Two pretty starkly different genres. I think La Boca is vastly better in absolute terms, easily one of the very best in the city, but it's Spanish tapas and CP is upscale New Mexican. Both rooms are small, cramped, and fairly loud. I think CP works much better for breakfast, maybe go then instead?
And just because the chow gods would wish me a year's worth of eating nowhere but McDonald's if I didn't say it: reservations at two restaurants for the same meal is kind of a party foul, so please do cancel one soon.
