We found the 6th st diner to be excellent we. Went for 2 breakfasts 1 lunch and 2 dinners over 28 nights. The food and service was excellent each time. As for the Green and Co. I would agree that it is underused however the food on offer was excellent, we are not vegetarians. With regard to the Olive Grove it was what I expected as I knew about the changes. But it is not trying to be the same as on Iona. A number of people I have talked to think that what is on offer on Arvia is better than on Iona, overall Interestingly they Olive Gove is now open for the MDR breakfast which i cannot remember if that was the case on Iona. I mean the venue not the Olive Grove.
