What a concept!!! I LOVE and have a complete adoration for hotdogs. May sound weird but it started in college as a late night bar snack and now it's just an obsession. That being said - I tried to go to happy dog a few weeks ago around 1:30 and they said the kitchen was closed even though their posed hours say the kitchen is open until 2am. I reallly do not like when places close before their posted hours. It's not like the place is in the middle of the action. Regardless, about a week later I went back during normal dinner hours.
The "menus" are cute checklists where you select what you want on a hotdog. They range from the ordinary to the very crazy. I chose to go with mac'n'cheese, "everything bagel" cream cheese, bacon, and Momocho's Habenero hot sauce. HOLY ----!!!! It was delicious --- however almost inedible toward the end due to the concentration of hot sauce (my own fault). They also have suggested combinations if you are a hot dog novice. Lively atmosphere. I know they have live music as well (did not catch that). And their tots were delish! Fun experience with lots of beers to choose from. Will definitely be back!
