The wife and I ended up our little Valentines day outing in Gruene and had a late lunch/early dinner at the Gristmill. we sat out on the back deck overlooking the Guadalupe River. The food was very good. If you go, be sure to get their hand breaded onion rings ... OMGoodness, some of the best I have ever had anywhere.
