how far is I from Lakewood Church?
is it walking distance?
is it a safe area?
I am not sure there is any area in Houston that is safe. It is within walking distance, but I would not do it after sunset. It is a little over a half mile to Lakewood Church, and then under a 12 lane highway. There are not a lot of choices for restaurants within walking distance. There is two hamburger joints, and a Chinese restaurant within a quarter mile.
If you look at the La Quinta site they should tell you what eating places are close. I again stress that like all other areas in Houston proper it is not safe on the streets at night.
