i've had peruvian before at el pollo inka (and if matsuhia counts...then that one, too), but tried it again recently at mario's peruvian over in the hollywood-ish area. for the most part, good stuff.
to start off, the plain white ROLLS were sort of dry and boring, especially since they come with butter in plastic, peel-off-lid cups. the MUSSELS and SHRIMP CEVICHE appetizers both tasted fairly good, but not very different from each other, since they both had the same heavily citrus-spiked mix of red onion and tomatoes. the only thing was that ceviche was made from what seemed like pre-cooked shrimp rather than raw shrimp that had been cooked by the citric acid.
though the appetizers tasted like each other, the main dishes were all very different and interesting. we ordered by number. 26 is the SALTADO DE MARISCOS a stir fry of octopus, squid, shrimp and vegetables, and french fries - that just makes me smile :) flavor of the dish was deep, but the squid and octopus were a little chewier than i like.
14 is LOMO SALTADO - beef and french fries :) sautéed with red onions. the beef was cooked to well-done, leaving it slightly dry for my taste, but thats just an excellent excuse for a gratuitous squeeze of the bottle that has a somewhat spicy green salsa.
PESCADO was the third dish, but it was totally unmemorable. i cant even remember the dishs name nor number. It might have been number 29, the PESCADO FRITO, but I think it was the number 30, PESCADO CHURRIANO. just. can't. remember.
all in all, pretty good food, but a little far for me to get to (i'm on the westside), especially since it closes at 8.
