We've been hoping for solid fish tacos and a taqueria or equivalent trully worth frequenting. A number of the local authentic taqueria's just don't have the environment that you feel comfortable frequenting, even though the food may be solid.
Chubby's tacos on 9th street changes that - no, it is not less rustic or more clean inside - its still an interesting crowd - but at least it is more welcoming. The fish tacos (though pricey at $4 each) are very good. Large pieces of tuna with a spicy sauce - these aren't Tijuana style, but they are very good. The other "regular" tacos are less expensive, down to $2, but also very good. A huge salsa spread lets you choose your heat level and flavoring. The store is tiny - we find it just as easy to get carry out and eat somewhere close - maybe the lawns over on Duke campus.
