Bymark is pretty swanky. It's part of that whole business district group of resto-bars that get all the action. There's Kei which is the new kid on the block, old standard, Canoe and Bymark. I imagine the power-lunches at this joint can be pretty intense, but I've always liked it at night for cocktails before hitting a dance floor. One, because that's the quietest time, and two, because the service is excellent. It's a good place for a date and if you like to eat at the bar and have good conversation with the bartender. But, my top pick of when to bring someone here, would be to impress a potential boss, or mentor. It's more ego than sex for sure.
