I've had a promotional email from Frankie and Benny's about 'unlimited breakfast'.
The terms are, you can reorder another breakfast for free, but, you must have finished your entire plate, and, you can only reorder the same thing, breakfasts can't be shared.
I should say if no one has been to Frankie and Benny's that this isn't a buffet, it's breakfast made to order.
Who is going to want to do that? You might say want some pancakes after a fry up, but who's going to order a fry up, then another one, surely if you're still hungry after eating then their portions aren't big enough anyway!
