Some Houston friends of ours have a very sick child, and they are spending a lot of time at Texas Children's Hospital. We would like to get them a gift certificate for a delicious and nice dinner someplace not terribly far from the hospital. Unfortunately, I don't know their food tastes, but we would like to treat them to a very very good meal -- I suppose something with a broad menu or widespread appeal, i.e. French, Italian, etc., might be safest. I do not know Houston at all, so any recommendations would be much appreciated. Thanks for any help you can give.
