I don't believe there's a such thing as a bad time to visit Wasted Grain. I had a blast there under its past life as Martini Ranch, and I still think it's awesome now.
Here's the deal. It has:
-A cool little local music venue on the first floor
-An awesome patio, now equipped with *two* bars
-A real groovy lounge upstairs
It really does cater to the tastes of everyone. You can get your club on at night, but it's a good spot during the day as well. No one who works here is a douche. I'll return. I'll even recommend it to anyone!
