A bunch of us recently dined at Volt and I have to say that we all enjoyed it (and we're fairly finicky about our food). The drive wasn't bad, but some of the initial parts of Frederick were a bit seedy ... the street where Volt is charming, though (there is also parking right next to Volt).
Service was exceptional and well-coordinated. We were a high maintenance table with a few folks who had allergies and they accommodated everyone without reserve. There was one course that none of us enjoyed (the sweetbreads ... not because we don't care for sweetbreads, but none of us are fans of fried fried food and that's about all you tasted with that particular dish - the only real miss of the evening). When our waiter noticed that none of us finished this dish, he asked what he could do to compensate for it and we said nothing, the dish just wasn't to our liking. For the following course, he brought us a wine pairing on-the-house which was thoughtful and we all enjoyed it. Some of us opted for the wine pairing throughout the meal and we agreed that the pairings were very well executed with some notable standouts - pork belly/burgundy and fois gras/white burgundy (I think) were excellent. Get the pairing and definitely get those two dishes. Not sure why all the negative comments on desserts, but the one that we had (chocolate, peanut something) was quite good.
All-in-all, a great dining experience ... we're definitely looking forward to returning. If paying a decent amount for dinner offends you, then you'd probably want to go to one of the other nice restaurants in Frederick that may not be as expensive. However, how much you spend is on par with what you'd spend at any similar restaurant in DC.
