I love a place that consistently surprises me, yet is consistent with getting the basics right. Bar Marco has that: lots of variety, but always excellent service and wonderful cocktails.
I've only been for brunch and rounds so far (dying to check out No Menu Monday but just haven't made it in yet), but each time has been great. The servers and bartenders are just top-notch. The bartenders are pros at the 'tell us what you like and we'll make a cocktail out of it' game. And this is a spot where the bar and the restaurant are truly two parts of the same whole: the servers are knowledgeable about the drinks too.
I think what I love so much is that Bar Marco is simple and yet exciting. Your brunch order may just be eggs and country potatoes, but the eggs will be dressed up in fresh ingredients and bursting with flavor. They don't have a massive selection of booze behind the bar, but they can make pretty much anything you can dream up, and make it really well.
While they do have a nifty little cocktail list, the sky is really the limit. This is one of my favorite places to order a Blood & Sand, a drink at the top of my list. Their brunch cocktails are fabulous as well and very refreshing in the morning!
As long as Bar Marco keeps serving up great scotch cocktails and friendly service, I'll keep stopping in.
