I'd be grateful for suggestions for an upscale but interesting place to take a group on a Friday night in Dallas. There will be about 15 of us, and we'll be staying in Los Colinas, but can travel a bit. Looking for something with attractive surroundings, a decent wine list, good service, and of course good food. A steak or seafood place would be fine, as long as there are some vegetarian options. It's a business dinner for a well-traveled group, if that helps. Anything interesting that would fit these criteria? Thanks!
