Decided to try the wagyu beef burger (medium rare) with the burpple one for one offer.
The buns were great - crispy while still retaining its fluffiness. However, the beef patty was not cooked with the same consistency - it was slightly overcooked at the left side but medium rare at the right side of the beef patty. Could be an anomaly, but I wouldn't try the wagyu beef burger again.
Nevertheless the place has a good vibe and will be back to try their other dishes on the menu.
