It's an annual event to hit Nitty Gritty on (or around) my birthday. I always enjoy the new mug and whatever I can fit into it that day. :)
On top of the mug and free drinks, I do enjoy their food - hopping around the various burger options depending on how I feel that day. The food is consistently good and always prepared as ordered.
It's a clean, friendly environment. Service is always friendly and prompt. I have no reservations taking the family there, or meeting with a work group for drinks.
