***HIGHLY RECOMMEND*** My order came to £12.50. I had the "Grandioso burger", which came with a free drink despite not being a meal, which was a nice touch. It's a great location, say a 5-10 minute walk from Old Street underground station. I spoke to the owner after I ate my food. He is genuine, friendly and very ethical, based on the conversation we had regarding his pricing and how he sources food. The burger was huge, great value for money and very tasty, especially the sauce. The burger came with the right amount of sauce and cheese. It's a bit messy to eat, but thankfully this place sees that and has the sense to provide good quality wet wipes and tissue/napkins, all free of charge. Every burger on the menu (excluding any vegetarian or vegan options, not my thing lol) sounded great, I really struggled to choose. I spoke to the owner and he talked me through the menu and helped me make the right decision. Next time I am going to try one of the chicken burgers, one of which is grilled, the other fried. All of the beef patties are either Aberdeen Angus or Wagyu. There are places to sit, but there isn't much space inside. There are no toilets. You can pay by cash or card. Drinks wise, there are fizzy drinks/sodas and milkshakes. There are probably other options like water and juice etc, but I can't remember. I scored the atmosphere 3/5 because it isn't a restaurant "like that", but I would happily go again and eat in :) If I had to critique one thing ironically it would be the size of the burger! It's so big it can be hard to eat, so please provide a very sharp knife to cut the burger in two, or ask customers if they would like that to be done by the chef. Attached are pictures of what I order.
