I have never bought deals for restaurants from the internet but have made frequent use of dockets for cheaper meals or more usually the buy get one free deals. I often check www.shopadocket.com.au which alsp has other offers.
I've purchased several deals from Cudo and have had great meals at places I probably would not have patronised previously. It gives a good indication of value for money (at the normal price) and I've only had one meal that I would consider wasn't value for the price indicated on the menu but the food was good, just not enough.
Yes, my husband buys them! We use them when we have something else to do in the Sydney, (nsw) CBD. If it saves me cooking that night, that’s great! We have bought the Lindt cafe one a few times, & brought home 2 lots of the food in our little containers, to have for afternoon teas at home!
I buy online deals for meals at restaurants quite often! They are such good value and it is good to be able to try something new without having to pay full price! Even if the meal isn't as good as you thought it might be, at least it was cheaper! A good way to experience something new at a discounted price. A lot of the time I would always do some online research and read some reviews about the restaurant before purchasing the deal.
We used to a lot, but thy haven't been coming into my husbands computer for a long while now. We used to like the lunch ones. In Sydney the best one for us, was a bucket of prawns & a bottle of wine at a restaurant at Darling Harbour & 1 night we had a deal for an Indian restaurant, also at Darling Harbour, & the fireworks started up, as we were leaving the restaurant! We thought that was because it was our wedding anniversary! But we later found it it wasn't because of that! They light them every Saturday evening, at 8.30!!! It sure made our evening feel special though!
