Creative, house-made-bun burgers with standout filet mignon option; solid service, mixed fry/steak feedback, fair-to-good value for Park Slope.
Why it gets a B- for overall quality
XO Burgers delivers reliable neighborhood quality through strong burger execution with house-baked buns and juicy patties and attentive, friendly service, but inconsistent cooking—particularly with steaks and fries—and variable service speed prevent a higher grade. The clean, bright 5th Ave location appeals to families and burger enthusiasts seeking elevated casual dining without pretension, though it lacks the distinction of top-tier burger destinations.
Restaurant Summary
A bright, clean fast-casual spot where house-baked buns frame juicy burgers, XO Burgers feels like a neighborhood upgrade on 5th Ave. Staff are friendly and attentive, often running food to tables. One diner said the rib burger "melted in my mouth" while another praised the super clean space. The cooking leans elevated classic rather than experimental, with premium touches like filet mignon burgers and a tender rib sandwich. Expect solid seasoning, a soft bun, and saucy builds; fries read mixed, and steaks can be hit-or-miss. It suits folks who enjoy hearty, non-smash burgers and do not mind a small premium for better ingredients. Families do well here: there is a Baby Burger, chicken nuggets, fries, and shakes frequently mentioned by happy parents. Vegetarian diners get a potato-and-mushroom burger plus salads, though items can sell out at busy times, so backup choices are wise. Portions satisfy most, but ask for extra fries if you are sharing.
