Went here spontaneously the other night and had a great time! You can pick and choose all the components of your burger and apparently there are are like thousands of combinations. I had the venison with blue cheese and some other stuff and hash browns as a side.
Be careful not to order too much, I had nachos as a starter (admittedly not the best but still good) and I was already full for the burger, still ate it as it was super tasty!
Apparently gets really busy so maybe don’t go on like a Saturday night or something as the service might be slow.
All round great place though!
