Professor Moriarty's is American fare in an informal setting on the main downtown thoroughfare in Saratoga. If you get lucky, you might be able to get a seat out next to the sidewalk so you can people watch and view the goings-on of downtown Saratoga while you eat.
The food here is along the lines of deluxe burgers, chicken sandwiches, and salads. You'll find it is one of the lower priced restaurants in Saratoga (save for fast food and the Subway down the way).
The food is tasty, the way good burgers should be and the atmosphere is laid-back. I recommend you save your cash by eating at Professor Moriarty's and then you'll have more money to wager on the horses.
