Ate at Bistro St. Marks tonight and was surprised to see hamburger on the menu. The waitress told us it had just been added in response to popular demand. I tried it and can report it is a winner. It was cooked medium, exactly as to order, a little charred on the top and juicy within. It wasn't gussied up in any way -- just good meat well prepared. It came on a toasted English muffin and melted cheddar cheese, accompanied by Bistro's usual fine pomme frites. They threw in a bit of iceburg lettuce, sliced tomato and red onion rings on the side (nothing special but welcome). Washed down with Brooklyn Lager, this made a most satisfying meal. Of course, being Bistro the burger was $13 -- but it's damned good. Congrats to Bistro for adding this comfort food fave to the menu, and carrying it off so well.
