It's known as "The Burger Joint", but here's the secret - they actually sell pretty darn fantastic pizza. And waffles. And beer. And did I mention waffles?! When visiting Cape Town, pop in at Hudsons on Somerset Road in Green Point. The staff are great, the food is great, the atmosphere is great.
Be sure to make a reservation if you intend going between 18h00 and 21h00 most nights - it's super popular and you're unlikely to get a table otherwise.
