Good food, less trendy

Hi all,

I'm looking for a restaurant that has good food, friendly astmosphere, but is less trendy and flamboyant. I'm looking for good (medium, not large, not miniscule) portions and flavor without all the carved vegetables, food sculptures, and square plates. Also, not necessarily looking for a hole-in-the-wall best $5 burrito place either.

Am open to any cuisine, somewhere along the peninusula anywhere between and including SF and San Jose.
