I'm working away at the the moment and staying at a Premier Inn. As it's paid for by the company, brekkie's included, so of course it'd be rude of me not to try it ... everyday.
I've had bad experiences with large chain hotel breakfasts - I won't name and shame the Ibis in Crick (M1 northbound, Junc. 18) - but in the 3 weeks I've been at this Prem. Inn, I've never had a bad one!
The picture below doesn't do it justice - I ain't David Bailey! - it's a one-of-everything-except-the-veggie-sausgage - and contrary to the posters on the wall in the hotel ... you do get a knife with it. :o)
So, if you have to work away ... and stay at a chain hotel ... and breakfast is included ... my advice is Premier Inn!
