I was recently asked back to try out the burgers at Burger Theory at Kongs in Cardiff. I’d been a few times in the past and did a blog post after my second visit to the pop up kitchen on St Mary’s Street. I’m glad to say that things have improved quite a bit since then as it was still new on the scene and I did have a couple of issues on both my first two visits.
I decided to take my younger sister and her boyfriend to see how it faired against some of the other burger places a 16 year olds frequent in Cardiff these days and to get a younger persons perspective. I was offered a £35 voucher towards food so I paid extra for the rest of the food and drinks on the visit. Seeing as I wanted to compare against how they had progressed since the 18 months after they opened I thought I’d opt for the same burger I ordered on my first visit the Kimcheese featuring Beef patty, melted cheddar cheddar, kimchi, pulled beef rib with black pepper glaze, chipotle mayo (£11.95).
I was going to order the cola ham hock dirty fries I’d seen on the menu previously but they were a special and been replaed by the “You have goat to try these fries”, which were a Caribbean take on dirty fries, which consisted of Fries loaded with goat curry, melted cheese, lime and coriander aioli, pineapple and scotch bonnet sauce, coconut flakes.
My sister opted for the Cheese theory with Beef patty with crispy bacon, melted cheddar, house pickles, Dijonnaise, house ketchup (£8.75) and her boyfriend went for The Sherriff with Beef patty with crispy bacon, melted cheddar, onion rings, BBQ sauce (£9.25).
We fancied a chip fest so went for two standard fries (£2.95 each) and a side of halloumi chips (£6.50).
Soft drinks all round for the teens whilst I sipped on a pint of Tiny Rebel Cali till the food appeared out of the kitchen.
The Kimcheese burger had grown since my first visit and was an absolute whopper of a burger to be fair. I was close to doing a few tricep dips off the edge of the bun to allow my jaw to take it in for a bite. There was a lot of juice and I was glad I had my side of the table to myself so I didn’t drown the person next to me whilst I chomped away.
There was a decent amount of meat content with the patty, beef rib and combined with the other fillings it did taste really good. Again though there wasn’t much kimchi going on. I don’t think I had any of the advertised fermented Korean staple in my burger the first time I visited and I struggled to find much in it this time unless they had done a batch of their own quick pickled kimchi but there was none of the expected pungent condiment in my burger this time either. Apart from that I was pretty happy with the burger.
There was a bit of a mix up with the fries but probably due to me using the voucher to pay at the start for part of the meal as the server wasn’t sure what to do with it. I ordered one portion of the goat curry dirty fries and two portions of the standard ones but two goat ones came out. They immediately gave us a serving of the standard and let us keep the other goat curry but wasn’t sure if I’d been charged for the two goat curries. I’d had £35 towards the food, which came to around £55 in the end so I wasn’t bothered too much about going back and checking with them or causing a fuss.
The goat fries were amazing though and a great addition to the menu instead of the usual pulled pork or chilli beef you tend to find at most burger houses when opting for some dirty fries. They were a slow burner mind as the first couple of bites I thought oh, they aren’t too bad but a minute or two later I could of done with someone fanning me with a palm leaf whilst squirting my mouth with a super soaker 2000 filled with milk.
Not that I was complaining, I was expecting it to be hot spice wise but for me the meat could have been a tad warmer. They were pretty epic though.
My sister has an obsession for halloumi fries and was very impressed with Burger Theory’s take on the deep fried slabs of cheese and so was I. Portion size was generous and they looked exactly like chips, I thought they had brought out two different thickness of potato kind at first until I bit into one.
She also smashed the Cheese Theory burger and gave it a massive thumbs up along with her partner who said it was the best burger he’s ever had. He attempted a stab at the goat dirty fries and like me thought they were fine at first but when the heat kicked in he bailed. They both enjoyed the standard fries, although they didn’t quite manage to finish them off. Not from lack of trying I might add, they were just stuffed from the burger and other bits and bobs.
I was a lot happier with my food compared to my first and second visit. The Kimcheese burger was still lacking on the Kimchi front though as I’ve always got a tub to hand in the fridge at home I was looking forward to a healthy portion in my burger.
The goat curry fries were a really nice change and if you like your spicy food, keep with them as they seem quite tame at first but they don’t take long to catch up with you when you’re least expecting.
I’ve heard rumours that Burger Theory will be opening up as a standalone restaurant in Cardiff in the near future so keep your eyes peeled on socials. I’m hoping they carry the bottomless burger brunch they do at the standalone Bristol venue to Cardiff too as that will be unreal.
If you’ve not been to Burger Theory before, it’s located at Kong’s Bar on St Mary Street, which is a basement bar next to Turtle Bay.
