Here's my take on Manchester food spots:
New Sami on Whitworth Street, I absolutely love this place. You can get all you can eat sushi and lunch time for £10. Can't say better than that!!
Bem Brazil on great ancoats, Similar to places mentioned before. All you can eat, salad bar and they come round with meat. Just hold of on the crap stuff like the sausages and wait for the good meat like the steaks.
There are a couple more of these dotted around town.
Tropiero off sackville street and another one near deansgate.
Simply Delish, is a great little deli for lunch or breakfast and is themed on healthy eating. Great salads, sandwiches, home made soups, hot specials.
Great variety and specials everyday. Fantastic for dieting.
