I just got home from my second dinnner at Pyramide, a new Mexican restaurant on 5th Avenue between 12 and 13. Overall, this restaurant is a welcome addition to the South Slope dining scene. The food is tasty and well prepared and the service is enthusiastic. I had the guacamole (prepared tableside) both times I went and thought that it was well prepared using very fresh ingredients (as a side note, I noticed that the tomatoes, onions and jalapenos were perfectly diced).
I have eaten (or tasted) the tacos al carbon, a shrimp special, the chicken chilaquiles (they call it a layered enchilada) and the boneless crisy half chicken. They were all excellent - bursting with flavor and well prepared. The half chicken managed to be crispy and juicy at the same time. The shrimp had an excellent sweet-and-savory flavor.
Pyramide doesn't have a liquor license yet but they have an innovative workaround - you get a beer or a glass of wine on the house.
I understand that they are offering weekend brunch in addition to dinner.
I only have one quibble - I wish the corn tortillas were homemade (a pretty high standard but after having fresh tortillas at the Red Hook ballfields, I can't get enough).
I recommend Pyramide and think it is well worth trying so please do so.
