Like the inside of a piñata, Puerto Marquez jabs at the senses with vivid blasts of color and cheerful pop-mariachi music (with videos!). As fun as it is, the atmosphere of the place barely hints at the multisensory pleasures that will soon grace your plate. The restaurant—sadly remote in an almost-Gresham strip mall—specializes in seafood; if you opt for the more common Mexican standards, beef chimichangas and whatnot, you may be underwhelmed. But go for something coastal, like the Puerto Acapulco, for example, and you'll feast (possibly for days) on shrimp, chicken, cheese, beans, rice and avocados, served with tortillas. Seafood empanadas don't look particularly impressive, but the crust is crisp and delicate and the shrimp inside perfectly tender. The ceviche ($8-$14) could easily be a meal all by itself. There are several varieties—the light and citrusy whitefish version is hard not to inhale. Between the ceviche and the free chips with beans and salsa that come as appetizers, you might happily spoil your appetite. But if you can pull it off, try a made-to-share house special seafood platter, with shrimp, oysters, halibut, mussels, veggies and rice ($59.95). Margaritas, like everything else here, are enormous and tasty.
