Having read a few posts on twitter about the availability of bases, we did pop into the restaurant at lunch time to ask if they had stock and were advised to book a table. This was a good move. When we returned for our 4.30pm booking, the place was heaving.
As well as the aforementioned salad bar unpleasantness we witnessed, I noticed there were croutons in the iceberg lettuce and the chance of cross contamination problems at the salad bar does seem high. If you have strict dietary needs then remember to raise them with your server to ensure they are met... don't rely on other diners being as careful as you are with hygiene and food!
