    Brilliant neighbourhood restaurant! Had a family meal yesterday and we all thoroughly enjoyed ourselves. Food was delicious and the staff were so friendly. Would highly recommend and would go back again.

    Always such a pleasure to dine at the Brass Onion, from the minute you arrive the incredibly friendly staff are on hand to give you the best possible experience. The food never fails to deliver, from the coffee and fresh squeezed orange juice to the big breakfast and french toast - divine! I am living in the UK and whenever I am home to visit the Brass Onion is always our go to for family gatherings big and small - we have celebrated lots of happy moments here - thank you to all the truly gorgeous staff for making this moments special!

    I ordered the Messi burger. Around the edges were fine but when I bit into the center of the burger it was cold. Reheated brisket.
