For those not aware, this is the new slider burger concept open on Pine just down the street from Kearney. Today was opening day and I went. Yummy burgers - nice and juicy on the inside, but they definitely have some pink, so you may not like it if you like your meat well done. The side is a fries and thin onion rings combo, which was pretty good but not outstanding. The options I didn't try were a vegie-burger option, gelato shakes, and a salad alternative.
I'd say it's in the top 5 of burgers in the city. Definitely more tasty than other downtown options (e.g., Bistro), but I'm not sure that they be able to handle large volumes of people if it gets popular, so service could be the downfall. Wait times will likely get to be extremely long in the next few days, so go before the buzz hits.
Note: Carry out only, no sit down service.
