The best restaurants in United Kingdom serving Argentinean food

Waited 25 minutes for some basic sides as snacks - staff said it was our problem due to the wait as their internal internet wasn’t working and we should have come sooner so needed to wait. Refused a refund due to time constraints as “didn’t know how” and then proceeded to verbally abuse in Spanish to a colleague. Reported to box park management who were nothing but helpful so no reflection on them, but the GM of the Argentinian grill establishment should be ashamed. Ordered from Poptata street fries instead - great food and service

Visited today with family. The place was empty. No atmosphere, staff surly and quiet. Ordered cheese on toast, big mistake, I haven't a clue what cheese was used but it was awful. Almost curdled and for a cancer patient going through treatment I cant afford to eat food that looks curdled. We left our food and certainly wont be returning. Tip for the future - use a decent cheddar or Cheshire cheese and not cheap rubbish
