I hadn't been to this venue since it was Margarita Rocks I believe? It appears as though they did a fair amount of remodeling before changing over to Wasted Grain, but for the most part the layout and overall vibe seemed to be about the same.
I stopped in here for my boys Bday party the other night since he had a table by the DJ booth upstairs in the back area of the venu and it was cool - decent music - so/so crowd, but we had fun at the table area although it was really hard to be able to talk to each other since the music was so loud at the table near the DJ.
I would probably never want this precise table again since it's no fun to have to yell into your friends ears whenever you want to say anything.
The staff here seemed pretty decent, but overall the whole experience was just okay/average for me. I can't really think of anything major to complain about, but at the same time I don't have anything exceptional to say about this venue. I only noticed a few major upgrades since it was another place - more TV's added and they cleaned things up slightly, so it's a bit more upscale currently. I definitely like the upgrades over the very grungy feeling I used to get in here.
When we did grab a few drinks @ the bar at one point it did seem like drinks were rather expensive here, but oh well - it is what is is ;) it is one of the larger venues in old town, so it's a cool spot to check out and bounce around in between all the rooms and the outdoor patio areas. If you are around it would be worth checking out, but don't have set your expectations too high if you know what I mean ;)
