Hi,
I am in houston, near westheimer Rd, I want to take my Gf for a good candle light dinner in the weekend, please suggest some locations, We prefer to eat, Chicken, Steak, Shrimp, Fish

I'm not in Houston, but I did a quick Google search for "houston candlelight dinners" and came up with a plethora of places.
