Best hotdog(s) I've ever had. The toppings are phenomenal. The space and design details are great and the concept (once the crowds die down a little and some opening kinks are worked out) is perfect for a very fast, very cheap meal. They have 4 taps of local beers, and then a very decent canned beer list (Oskar Blues and the like).
My only complaint concerns the VERY young (most looked 18 or under), VERY inexperienced front of the house staff. It matters little since its a take-a-number type of place, but the girl taking our order was dumb as a box of rocks and had zero social tact.
Me: "...and a side of fries please."
Her: flatly "We don't have those anymore."
Me: *looks back at the menu* "....Wasn't your grand opening yesterday? Do you mean you just ran out?"
Her: "Ummmm...*stares vacantly* we just like, don't have them."
-long pause-
Me: "Onion rings then."
I just thought it was funny. It does nothing to dampen my enthusiasm for JJ's!
