We went on a Wednesday night and the place was buzzing. Waited for longer than usual (> 45 min) before a female staff offered us a complimentary milkshake, and kindly explained that the long wait was because one of their waffle machine was down.
This kind gesture and service improved our overall experience. Also wanted to shout out that the milkshake is thick, creamy, consistent - it actually tastes much better than the waffles haha.
