I've now had all of the tacos at Nick's Crispy. I recommend: both fish tacos. I do not recommend: all the others.
The baja fish taco came this time with a large piece of mahi mahi, very fresh and moist, in the same powerfully flavored beer batter. Fresh shredded cabbage, chile powder flavored crema, and a griddled tortilla make a might fine taco. The grilled fish taco came with excellent wild salmon, the same cabbage and tortilla, but with a cilantro crema. Both about $3.
The other meats range from okay (carnitas, carne asada) to poor (greasy, tasteless chicken). But even the good ones are about $3 each and come with beans and lettuce. Might as well spend half as much and go to a real taqueria or truck for those tacos.
