I’m going to stay with a friend for few days over the bank holiday – thankfully I know her well enough to say what I am and am not eating.
When I’m going to be eating out , I check restaurant menus in advance, and get in first with suggestions of where to go – harder if you’re meeting new people though – or events with buffets, although the “no thanks, maybe later” would work well in that situation.
I found a local Korean restaurant looks very BSD friendly if I avoid the rice and noodle dishes, and this evening am going to Prezzo having checked out that they have a number of salads that will be fine if I adjust the dressing. The weekend I’m away there’s an amazing cliff top restaurant that does an amazing Sunday Roast – that should be fine if I just leave the potatoes. (or maybe have a tiny one!)
On the Alcohol front, maybe say you’re driving and stick to water or diet tonic? – Or simply say that you don’t drink alcohol (and hope no one tries to ply you with orange juice!)
