15/11/2025: Really good burgers and friendly staff. I've often passed by Holy Cow and often see lots of guests in there and you can understand that. Will definitely come back

25/10/2025: We have been coming to Holy Cow a few times a year for a number of years and it used to be our go-to place - unfortunately it is no longer and today's visit was probably our last. Tried the milkshake for the first time, which on the website is called "maybe the world's best" - maybe they should change this to maybe the world's thinnest as it tastes more like cold sweet milk, where it is difficult to taste the difference between the vanilla and strawberry versions. Mentioned it to the staff and got the answer - "That's completely normal". After a short wait the burgers arrived where two out of four were closer to rare than the usual medium rare - luckily we were able to swap between each other so everyone was ok as we didn't have time to complain about it. The amount of filling and especially truffle mayo was almost non-existent (compared to before) so the difference between our burgers was hard to see and taste. Luckily we got a little extra truffle mayo, but not optimal and was the last straw to take away the good atmosphere. The fries were great as always (although with an extra hair that my son removed from his portion). Accidentally discovered that we had paid for ketchup for two of our menus, when apparently only mayo is part of the menu. This was not mentioned when we ordered at the checkout. I mostly wanted to give 1-2 stars but the quality of the ingredients is good and maybe we were just unlucky today.
