Best burger in town.
While Burgatory offers a trendy atmosphere and crazy flavor combos (and does it very well), Tessaro's gets back to the basics and makes just a solid burger.
I recommend the BBQ burger with the Hot sauce, but can vouch for the Gourmet Kelley and the Cajun. Both delicious.
And even if you hate potato salad, I urge you to sample theirs. It's made with mustard as well as mayo, so a totally different flavor experience.
