Laurus and Blackhawk Grille might be the kind of venue you are looking for. For steaks, try Forbes Mill Steakhouse. All are in the San Ramon area.

Go to Esin in Danville at the Sycamore exit from 680, or Bridges in downtown Danville. Both are good for lunch. Food is better (IMHO) at Esin. If you like desserts, Esin have a huge selection of fresh and seasonal yummies.

koi garden is upscale chinese - but probably not what you're looking for.
oasis (afghan) in downtown pleasanton has an upscale feel, but it's hard to recommend because the food is all drenched in the same sauce
most of my favorites in the area are the ethnic restaurnats - saigon (vietnamese), kadupul (sri lankan), rose garden (indian), pamir (afghan)
