RE: Beef on Weck in Saratoga
The sandwhich is pretty tasty if it has quality fresh roast beef, good horseradish and really good rolls.
I used to get it in Albany and Saratoga often. Usually the roast beef juices soak into the roll to give it a light gravy flavor.
In Saratoga you should also check out Hattie's Chicken Shack for excellent chicken, then go up the street to Cafe Lena where Bob Dylan made one of his first gigs after arriving from Minnesota. Lena's used to have good espresso and deserts.
