Very disappointing. I can honestly say I have never experienced such rude and arrogant staff. Rang up to book a table a few days before we planned to go and enquired about the £12.95/£15.95 set menu advertised on the internet. Was told as long as we ordered by 7pm we would could have the offer. Myself and another member of our party of four arrived first. Even though the restaurant was quiet there was certainly no warm welcome or pleasantries exchanged with the waiter, he just looked us up and down, marched us across the restaurant and slammed back the chairs for us. We then started to look at the menus and realised that the menu we had been promised was not there. I enquired about this and was told that the menu had changed over Christmas. I explained to the waiter what I had been advised on the phone and he asked me what I thought he could do about it, no apology or anything. He then called the manager out, who was very intimidating. I explained the issue and he told me I should have looked at the website, which I obviously had done so already, hence knowing about the set menu. There was no apology or anything and he was basically implying that I was lying. They were so rude that we went next door to the Thai Edge. If you have a choice between the two, I strongly recommend the Thai Edge! Gorgeous food and in contrast to the staff at Cielo, delightful, welcoming staff
