I've never been disappointed by the food, and this place has one of the best burgers in town. It's a good size patty, maybe 1/3 of a pound, with a signature blend of meat cuts that amounts to a juicy, flavorful burger.
Many places ask you how you'd like your burger cooked, and then no matter what you say it ends up medium or well-done. I've started ordering burgers rare just to ensure *some* pinkness to the meat. At Tessaro's, if you order your burger medium-rare, that's how you get it. The no-frills cheeseburger is delicious, but I'd also recommend the Bacon Bleu Burger.
All the sides are good. The potato salad is a fine example of the form. The servers are unfailingly up beat and the dining areas are cozy and warm (one room has a fireplace that's always going during the winter).
This place isn't getting a Michelin star any time soon, but this is a quintessential traditional neighborhood casual dining establishment and won't let you down.
