I went to Rodizio Rico this weekend, its a brasillian barbeque restaurant. They have an all you can eat buffet, its £22.50 a head but the meat is so succulent. If you could go for a massive workout and then go there a couple of hours later it would be amazing, you could just stuff yourself. I went to the one in Upper Street in Islington but there are 3 branches in London.

"At Rodizio Rico, our selection of meat is extensive and sure to tempt with delights including leg of lamb; beef in a variety of cuts from silverside to picanha, the heart of the rump; pork; chicken thighs and chicken wings as well as authentic specialities such as chicken hearts. You can also help yourself to the vast array of traditional Brazilian hot dishes and exotic salads available on our buffet, all freshly made to time-honoured recipes.
Everything at Rodizio Rico is expertly grilled to keep it succulent and full of flavour. If you have a preference for how your meat is cooked, just let one of our passadors know and they will offer you cuts from either the outside of the skewer so it’s well done, or from the centre if you prefer your meat rare.
No craving is too large at Rodizio Rico and our waiters will continue to serve you freshly grilled meats until you can eat no more. A pure carnivore’s delight – all you need is a hearty appetite!"
