I've been at a conference today. People were asked about their requirements in advance and there were a number of vegetarians, some gluten free and some dairy free, as you'd expect.
Lunch was a very varied buffet with a gluten free (but not diary free) vegetable soup, two hot options (one gluten & dairy free, one vegetarian) a selection of sandwiches, some gluten free, fruit salad and a hot pudding with custard. There was nothing specially prepared for the special dietary requirements but they were catered for and there was plenty to go round I.e.there was no need to worry about non-vegetarians eating all the vegetarian dishes.
At the breaks there were pastries, nuts, sweets and fruit. So again, nothing specially prepared as non dairy etc but there was an option for everyone.
Is this OK, or did the people complaining about lack of choice, especially at break have a point?
